BROOK WANTS TO KNOW WHAT MAKES GEORGIA TECH A UNIQUE SCHOOL.

LET'S HEAR FROM JOSH ON THIS ONE AS HE GETS A SPECIAL TOUR OF CAMPUS.

HEY, JOSH.

WE'RE FOLLOWING YOU, MAN.

>>> HEY, GUYS.

>> THANKS FOR HAVING ME AND THANKS FOR TUNING IN.

THERE ARE SO MANY AMAZING THINGS GEORGIA TECH HAS TO OFFER.

HAVING AN ENGINEERING DISCIPLINE.

GEORGIA TECH WAS FOUNDED IN 1885.

IT WAS FOUNDED DURING THE INDUSTRIAL REVOLUTION AS A WAY TO COMPETE AGAINST THE NORTH >> IS THERE SIGNIFICANCE TO THIS BUILDING?

>> THIS BUILDING IS TECH TOWER, THE FIRST BUILDING BUILT ON CAMPUS.

BACK IN THE DAY IT HAD ONLY 84 STUDENTS.

YOU COULD ONLY GET A MECHANICAL ENGINEERING DEGREE.

>> GEORGIA TECH DOES AN AMAZING JOB WITH ENGINEERING.

DOES IT OFFER OTHER MAJORS?

>> BUSINESS, COMMUNICATIONS.

IN TOTAL 130 MAJORS AND MINORS TO CHOOSE FROM >> BESIDE IT IS ACADEMICS, WHAT DOES GEORGIA TECH HAVE TO OFFER?

>> IT HAS OVER 400 DIVERSE STUDENT ORGANIZATIONS ON CAMPUS.

THE STUDENTS LOVE CHEERING ON THE YELLOW JACKETS AT SPORTS EVENTS >> AWESOME.

HOW MANY STUDENTS GO TO GEORGIA TECH?

>> THE VAST MAJORITY OF THEM LIVE IN GEORGIA.

30% OUT OF STATE STUDENTS AND 10% INTERNATIONAL STUDENTS.

>> IT'S TIME TO CHECK OUT MORE OF THE CAMPUS.

>> LET'S DO IT.

>> ALL RIGHT.

WHERE ARE WE NOW?

>> HERE'S A LITTLE DIFFERENT FROM THE TYPICAL CLASSROOM.

THE IDEA LAB IS HOME TO A COMPETITION.

STUDENTS CAN BUILD AND DESIGN ROBOTS FOR A CASE COMPETITION.

THEY CAN LEARN HANDS ON EXPERIENCES AND APPLY THEM TO THE REAL WORLD.

>> THIS BUILDING WAS REALLY COOL.

WHAT ARE WE STANDING IN FRONT OF NOW?

>> IN 1996 THE OLYMPIC SIZE SWIMMING POOL WAS BUILT WHEN ATLANTA HOSTED THE OLYMPIC GAMES.

GEORGIA TECH DECIDED TO BUILD AROUND IT.

ONE OF THE AMAZING THINGS ABOUT THE BUILDING ITSELF IS THE ROOF ABOVE THE POOL IS COMPOSED OF SOLAR PANELS DESIGNED BY GEORGIA TECH STUDENTS.

THEY HEAT THE POOL AND SUP LE METROPOLITAN THE POWER >> WHAT CAN STUDENTS DO IN THE BUILDING?

>> YOU HAVE SIX BASKETBALL COURTS, INDOOR SOCCER, BADMINTON, AND A CLIMBING ROCK WALL.

>> DO THEY HAVE CLASSES HOUSED HERE AS WELL?

>> YES.

YOU CAN TAKE A LECTURE BASED HEALTH CLASS OR ATHLETIC HEALTH CLASSES.

YOU CAN TAKE YOGA, WEIGHT LIFTING, AND FITNESS CLASSES >> YOU SHARED A LOT OF STUFF THAT HAPPENS INSIDE THE CRC.

DOES ANYTHING HAPPEN OUTSIDE?

>> YEAH.

TO MY LEFT IS THE FIELD IN WHICH OVER 20 SPORTS ARE PLAYED THERE.

IT'S COOL FOR STUDENTS TO TAKE A BREAK FROM CADEMICS AND ENJOY SPORTS >> DO YOU PLAY ANY SPORTS?

>> I PLAY INDOOR AND OUTDOOR SOCCER.

>> WHAT WOULD A STUDENT DO HERE?

>> BESIDES IT BEING A LIBRARY, STUDENTS WORK COLLABORATIVELY AND STUDY AS WELL.

>> THERE IS A LOT OF FLOORS.

HERE THERE ARE SEVEN FLOORS.

IS THERE SOMETHING DIFFERENT ON EACH FLOOR?

>> AS THE FLOORS GO UP IT GETS MORE QUIET.

IT'S MORE INDEPENDENT STUDYING AND QUIET HOURS.

>> THANKS, JOSH AND JORY.

WHAT YOU DIDN'T SEE IS TEACHERS AND PROFESSORS WHO PROVIDE A WELL ROUNDED EXPERIENCE AT GEORGIA TECH.

JOINING ME IS PROFESSOR CRAIG FOREST.

WHAT DO YOU DO AT GEORGIA TECH?

>> I'M A PROFESSOR OF MECHANIC -- >> WE HAVE QUESTIONS FROM THE AUDIENCE ABOUT THE INVENTION STUDIO.

FOURTH GRADERS FROM NOONAN CROSSING ELEMENTARY WANT TO KNOW HOW LONG IT TAKES TO BUILD THE INVENTION STUDIO AND HOW LONG HAS IT BEEN OPENED?

>> WE HAVE THE QUESTION ALL THE TIME.

YOU DON'T NEED A BIG ROOM TO GET STARTED.

GIVE THE STUDENTS THE KEY.

YOU HAVE TO TRUST THEM THAT THEY'LL BE RESPONSIBLE FOR THE CREATIVITY THERE.

>> WE HAVE ADDED ON YEAR BY YEAR.

>> IT'S BIGGER TO ACCESS 24/7.

>> THIS IS COMPLETELY FREE FOR A GEORGIA TECH STUDENT TO BUILD THEIR INVENTIONS.

>> CAN YOU SHOW CASE ONE ITEM BUILT HERE?

>> OKAY.

I HAVE ONE RIGHT HERE.

THIS IS A ROBOTIC SKATEBOARD WITH A LITTLE FOOT.

IT CAN PUSH YOU AROUND CAMPUS IF YOU GET TIRED MY KIND OF SKATEBOARD.

ALSO, THE STUDIO IS AS OLD AS A LOT OF STUDENTS WATCHING TODAY.

WHAT ADVICE DO YOU GIVE TO A STUDENT INTERESTED IN ENGINEERING?

>> ENGINEERS WORK TO SOLVE REAL PROBLEMS IN THE WORLD.

IF THAT SOUNDS LIKE YOU, YOU SHOULD BE AT GEORGIA TECH WORKING ON INVENTIONS, TOO.

YOU HAVE TO BE A TINKERER IN YOUR CLASSROOM OR YOUR BASEMENT OR BEDROOM TRYING TO BUILD GADGETS THAT MAKE THE WORLD A BETTER PLACE >> ENGINEERS ARE PROBLEM SOLVERS.

IMPRESSIVE, CRAIG.

YOU'RE THE PERFECT PERSON TO ANSWER THE QUIZ QUESTION.

IN MANUFACTURING, WHICH MATERIAL IS BEST USED TO CUT THROUGH A THICK PIECE OF STEEL?

HERE'S HOW THE AUDIENCE RESPONDED.

CRAIG, TELL US WHAT IS THE CORRECT ANSWER >> ALL OF THESE TOOLS COULD BE USED TO CUT STEEL.

THE BEST ONE FOR A ONE-INCH-THICK PLATE LIKE THIS IS WATER.

YOU TAKE 100,000 POUNDS PER SQUARE INCH OF WATER, MIX IT WITH SAND AND IT CAN BLOW A HOLE THROUGH THIS STEEL PLATE >> I WAS NOT EXPECTING THAT.

DA VINCI SAID WATER IS THE DRIVING FORCE OF NATURE.

HE WAS RIGHT.

IT LOOKS LIKE WE HAVE QUESTIONS COMING FROM THE AUDIENCE NOW.

MRS.

HAMILTON'S CLASS FROM MURRAY MIDDLE SCHOOL ASKS, HAVE YOU EVER BUILT A ROBOT?

>> WELL, YES.

WE HAVE ONE OVER HERE.

I DIDN'T BUILD THIS ONE.

WE HAVE BEEN PLAYING WITH IT IN THE STUDIO.

THIS IS A SIX DEGREE OF FREEDOM INDUSTRIAL ROBOT THAT CAN SERVE COFFEE OR BE USED IN CAR MANUFACTURING TO PUT PIECES OF THE CAR TOGETHER >> WILL HE DO A FIST BUMP?

>> HE COULD, BUT IT'S BUSY NOW.

>> OUR NEXT QUESTION COMES FROM MASSACHUSETTS.

HI, MASSACHUSETTS.

THEY WANT TO KNOW HOW YOU RECEIVE FUNDING FOR THE INVENTION STUDIO.

>> AS YOU CAN IMAGINE A PLACE LIKE THIS TAKES A LOT OF MONEY TO RUN.

LOTS OF COMPANIES MAKE DONATIONS BECAUSE THEY WANT TO HIRE STUDENTS WHO KNOW HOW TO DESIGN AND BUILD STUFF.

EVERY MONTH WE GET DONATIONS FROM COMPANIES ALL OVER THE WORLD.

GEORGIA TECH WORKS HARD TO MAKE >> ANOTHER LIVE QUESTION FROM VIRGINIA D. FROM TEMPLE MIDDLE SCHOOL IN TEMPLE, GEORGIA.

SHE WANTS TO BE A VETERINARIAN AND ASKS IF THE 3-D PRINTERS CAN CREATE CASTS FOR ANIMALS AND HUMANS?

THAT'S SWEET.

>> OH, ABSOLUTELY.

FIRST YOU WANT TO SCAN THE PAW OR THE ANIMAL TO MAKE SURE YOU HAVE A COMPUTER MODEL.

THEN IMPORT IT INTO THE PRINTER AND PRINT IT STRAIGHT OUT >> IN CASE MY DOG ROSIE NEEDS A CAST I'M COMING HERE.

TIME FOR THE NEXT QUIZ QUESTION.

YOU CAN SHOW US HOW SMART YOU ARE WITH YOUR SMART DEVICES.

OUR SECOND QUESTION IS -- WHICH OF THE FOLLOWING WAS INVENTED BY AN 11-YEAR-OLD?

TRUE STORY.

WAS IT 1, THE BAND AID.

2, FIDGET SPINNER.

3, HULA HOOP.

OR 4, POPSICLE.

TEXT ONE, TWO, THREE OR FOUR TO (201) 561-7140 OR SUBMIT YOUR ANSWER ONLINE.

IT'S TIME TO SEE IT IN ACTION.

JOSH?

>> I'M AT THE BRAND NEW INVENTION STUDIO AT GEORGIA TECH.

WITH ME, MY FRIEND JOSH WHO IS A STUDENT HERE AND ALSO A PROTOTYPE INSTRUCTOR AT THE STUDIO.

JOSH, WHAT CAN YOU TELL ME ABOUT WHAT A P.I.

DOES HERE AT THE STUDIO?

>> P.I.s ARE STUDENT VOLUNTEERS.

THEIR MAIN ROLE IS TEACHING PEOPLE TO USE MACHINES AND DIFFERENT TOOLS AND MAKE SURE EVERYTHING IS SAFE.

>> DO YOU HAVE TO BE AN ENGINEERING MAJOR TO BE A P.I.

OR USE A MACHINE?

>> I'M A FOURTH YEAR MECHANICAL ENGINEER.

THERE IS NO REQUIREMENT TO USE THE TOOLS.

>> THAT MEANS THIS PLACE GETS BUSINESS.

ALL THE STUDENTS HAVE ACCESS TO IT >> THIS PLACE GETS CRAZY BUSY.

WE ARE OPEN MONDAY THROUGH FRIDAY AND THERE ARE PEOPLE WORKING ON SCHOOL PROJECTS, ART AND PERSONAL PROJECTS ALL THE TIME >> TIME TO CHECK OUT THE SPACE.

>> COOL.

>> LET'S SEE WHAT THE HYPE IS ABOUT.

>> THE FLOWERS INVENTION STUDIO HOUSES OVER 25 DIFFERENT MACHINES AND MORE THAN 60 IN TOTAL.

THE MOST COMMONLY RECOGNIZED ONE IS A 3-D PRINTER.

HERE TO TELL ME MORE IS ABBY, A FOURTH YEAR ENGINEERING STUDENT HERE.

>> WE HAVE 3-D PRINTERS WITH PEOPLE IN AND OUT ALL DAY WORKING ON PROTOTYPES.

THESE ARE THE BEST MACHINES TO MAKE YOUR PARTS QUICKLY.

3-D PRINTING IS A TYPE OF ADDITIVE MANUFACTURING.

WE ARE ADDING MATERIAL ON TOP OF MATERIAL.

THEY ARE LIKE A HOT GLUE GUN THAT YOU CAN MELT WHAT'S CALLED FILAMENTS TO MAKE WHATEVER PART YOU WANT TO MAKE.

>> THAT'S COOL.

HOW DO 3-D PRINTERS WORK.

IT'S SIMILAR TO A PRINTER AT HOME BUT WE ARE USING INK-FREE FILAMENTS.

IT STARTS BY DESIGNING A PART IN A 3-D COMPUTER AIDED DESIGN SOFTWARE.

THEN TO A SLICING SOFTWARE TO CUT IT INTO TINY LAYERS SO THEY KNOW HOW TO BUILD IT.

AND THEN YOU SEND A PART TO A NORMAL PRINTER, JUST SEND IT OVER >> HOW LONG DOES A PRINT TAKE?

>> PRINTS TAKE FROM 20 MINUTES TO 20 HOURS DEPENDING ON HOW BIG IT IS AND HOW STRONG.

THIS PRINT WOULD TAKE SEVEN HOURS BECAUSE IT HAS TO BE STRONG TO HOLD A MOTOR >> MY PRINTER AT HOME, I CAN CHANGE THE SETTINGS.

CAN WE CHANGE SETTINGS ON THESE AS WELL?

>> ABSOLUTELY.

DEPENDING ON THE PART YOU HAVE AND HOW STRONG YOU WANT IT, YOU CAN CHANGE SPEED, WALL THICKNESS.

RIGHT HERE WE HAVE ALL KINDS.

YOU WANT IT TO BE 100% FOR REALLY STRONG.

0 FORTUNATE WOULD BE HOLLOW.

>> IS THIS THE ONLY 3-D PRINTING THAT EXISTS?

>> THIS IS THE MOST COMMON TYPE.

YOU CAN 3-D PRINT USING POWDER FOR A MORE PRECISE PRINT.

YOU CAN 3-D PRINT USING METAL WHICH IS REALLY ADVANCED.

THEN YOU CAN 3-D PRINT USING A BUNCH OF LAYERS OF PAPER.

THIS IS A MAP OF THE BUILDING WE ARE IN.

THEN YOU CAN 3-D PRINT USING RESIN WHICH MAKES A FLEXIBLE PRINT.

>> NEXT TO THE 3-D PRINTERS HERE WE HAVE THE LASER CUTTERS WHICH MIGHT BE THE COOLEST THINGS IN THERE.

WHAT CAN YOU TELL ME ABOUT THE LASER CUTTERS?

>> THEY ARE MY FAVORITE MACHINE HERE.

THEY USE REAL LASERS.

BECAUSE WE ARE CUTTING AWAY DIFFERENT MATERIALS IT'S CALLED SUBTRACTING MANUFACTURING AS OPPOSED TO THE ADDITIVE MANUFACTURING WE SAW.

>> IS THE LASER BURNING THE WOOD?

>> DEPENDING ON THE SETTINGS, IT WILL TAKE TIME.

SOMETIMES BECAUSE THE LASER IS SO POWERFUL IT LEAVES BURN MARKS AROUND THE EDGES.

SOMETIMES THE BURN MARKS LOOK COOL >> THIS ONE ONLY TOOK THREE MINUTES AS OPPOSED TO THIS TAKING 12.

>> EXACTLY.

>> YOU AREN'T PUTTING YOUR HAND INSIDE THE LASER.

ARE THEY USING COMPUTERS AS WELL?

>> ALL THE LASERS COME WITH THEIR OWN LASER SOFTWARE.

THE INFORMATION THEY READ FROM THE FILE ARE DIMENSIONS, DEPTH OF CUT AND THE SPEED OF THE CUT.

WE HAVE SOME PEOPLE THAT COME IN TO MAKE JEWELRY.

SOME PEOPLE THAT COME IN AND LASER ENGRAVE GLASSES FOR GIFTS.

>> WE HAVE MOVED ON TO A ROOM WITHIN THE INVENTION STUDIO THAT HOUSES SOME OF THE MORE POWERFUL MACHINES AVAILABLE TO STUDENTS.

WE HAVE TODD WHO WILL BE EXPLAINING ABOUT THE MACHINES.

WHAT ARE WE LOOKING AT?

>> THIS IS THE WATER JET.

IT'S REALLY USEFUL IN CUTTING THROUGH HARD MATERIALS.

IT CAN CUT THROUGH STONE, QUARTZ OR MARBLE >> DID YOU SAY WATER CAN CUT THROUGH STEEL?

>> IT SHOOTS HIGH PRESSURED WATER AND AN ABRASIVE CALLED GARNET WHICH IS LIKE A SAND MATERIAL.

THE COMBINATION IS STRONG ENOUGH TO PIERCE THROUGH WHATEVER MATERIAL YOU HAVE.

>> LASERS ARE POWERFUL AS WELL.

WHY ARE YOU USING WATER >> THE COOL THING IS YOU DESIGN THE PART IN CAD AND UPLOAD TO THE COMPUTER.

IT WILL ACCOUNT CUT THROUGH FOR YOU.

THE LASER CUTTER IS LIMITED.

YOU CAN'T CUT SOME MATERIALS BECAUSE THEY ARE TOXIC.

WHEN EXPOSED TO LASER.

ALSO, THE LASER ISN'T AN ABRASIVE.

YOU CAN'T CUT THROUGH A LOT OF MATERIALS.

METAL, YOU NEED TO CUT THROUGH IT.

IT'S DANGEROUS.

THE WATER JET JUST CUTS THROUGH FOR YOU >> WHAT PRODUCTS HAVE YOU SEEN CRAFTED FROM THIS MACHINE?

>> I HAVE SEEN A CHESS BOARD.

YOU CAN BRING IN YOUR KITCHEN COUNTER TOP.

CUT GRANITE, QUARTZ.

THOSE ARE A COUPLE OF EXAMPLES.

YOU CAN CUT STEEL PROPELLORS.

THIS ONE IS COOL BECAUSE IT SHOWS OFF THE FIVE AXIS CAPABILITIES OF THE WATER JET.

YOU CAN CUT AT ANGLES.

THAT'S ONE OF THE COOL THINGS YOU CAN DO WITH THIS.

IT'S GREAT.

ONCE YOU'RE DONE YOU HAVE A BIG STOCK OF MATERIAL AND ALL THAT'S LEFT IS A SCRAP.

YOU CAN REUSE THE SCRAPS TO MAKE ANOTHER PROJECTS, COOL.

>> I'M HERE WITH SAAD INSIDE THE INVENTION STUDIO WOOD SHOP.

TELL ME MORE ABOUT THE MACHINE.

>> SURE.

THIS IS THE CNC WOOD ROUTER.

ESSENTIALLY IT STANDS FOR COMPUTER NUMERICAL CONTROL.

WE TELL THE COMPUTER WHAT TO CUT, HOW TO CUT IT AND IT DOES IT FOR US.

IT'S GREAT BECAUSE IT USES SUBTRACTION MANUFACTURING.

YOU CAN CUT AWAY TO MAKE WHATEVER YOU WANT.

THAT IS CALLED CHIPS OR SAW DUST >> WHICH EXPLAINS THE VACUUMS IN HERE.

>> OH, YEAH.

>> AWESOME.

HOW DO YOU KEEP THE WOOD IN PLACE WHILE YOU'RE CUTTING?

>> THIS CNC IS NICE BECAUSE IT HAS A VACUUM TABLE.

YOU TURN ON THE VACUUM AND IT SUCKS THE EARLY MATERIAL RIGHT THERE AND KEEPS IT IN PLACE WHICH IS WHAT YOU WANT WHEN YOU'RE CUTTING SOMETHING THAT SPECIFIC >> EXACTLY.

>> HOW IS THIS DIFFERENT FROM A LASER CUTTER AND A LASER CUTTER USES A LASER AND BURNS INTO THE MATERIAL.

THAT'S HOW IT EDGES THROUGH AND CUTS IT.

THIS IS DIFFERENT.

BITS ARE A FAST MOVING THING.

IT CHIPS AWAY AT THE MATERIAL.

IT HAS AN AUTOMATIC TOOL EXCHANGER.

YOU CAN START WITH BIG BITS, LITTLE BITS AND THE MACHINE DOES IT ALL.

>> WHAT PROGRESS DO YOU MAKE WITH IT?

>> I MADE A TOPOGRAPHICAL MAP OF GEORGIA.

THIS ONE TOOK TWO HOURS TO CUT.

YOU COULD MAKE SHELVES, SOMETHING LIKE THIS.

CUT THE EDGES OF THIS.

>> IT CAN GET REALLY DELICATE.

IT'S EFFICIENT, FASTER AND CHEAPER.

>> THAT'S AMAZING.

STUDENTS CAN CREATE DIFFERENT THINGS HERE.

I BRING YOU PROOF IN THE FORM OF TWO NEW GUESTS.

JOINING ME ARE DEV AND HILL, A CURRENT STUDENT >> WE ARE EXCITED TO BE HERE.

>> IT'S AN HONOR.

>> IT MAKES THEM SUBJECT MATTER EXPERTS FOR THE SHOW.

THEY HAVE A LOT OF EXPERIENCE WITH INVENTING.

WE HAVE A QUESTION FROM THE AUDIENCE.

DADE, A FOURTH GRADER AT MALCOLM BRIDGE ELEMENTARY IN BOGART.

CAN YOU TELL US ABOUT AN INVENTION THAT YOU DEVELOPED PERSONALLY?

THAT'S A GREAT QUESTION.

WHAT HAVE YOU INVENTED?

>> A SAFER CUTTER TOOL AND A DEVICE TO HELP GUIDE NEEDLES SAFELY INTO THE SPINE FOR MEDICAL PROCEDURES.

>> YOU WON A COMPETITION FOR THIS.

>> BOTH WERE WINNERS AFFIDAVIT GEORGIA TECH INVENTOR PRIZE.

>> IT'S LIKE THE "AMERICAN IDOL" FOR NEWS.

THE LONGEST RUNNING STUDENT INNOVATION CONTEST IN THE UNITED STATES.

STUDENTS TAKE THEIR INVENTIONS THEY CREATED IN PLACES IN THIS STUDIO AND COMPETE AGAINST ONE ANOTHER FOR CASH PRIZES AND HELP ON THE START-UPS THEY ARE CREATING >> A NEEDLE GOES INTO THE SPINE.

>> THIS HELPS YOU SEE THE NEEDLE GOING INTO THE BODY GIVING X-RAY VISION INTO THE BACK.

>> VERY PRECISE.

WE LIKE TO SAY DEV HAS OUR BACK >> IN BETWEEN CLASSES I LOOK WORK FOR A COMPANY.

WE WON THE ADVENTURE PRIZE IN 2014 >> I'M STANDING IN THE WINNER'S CIRCLE AND I DIDN'T KNOW IT.

>> WISH FOR WASH IS A NONPROFIT THAT MAKES TOILETS FOR PEOPLE IN DEVELOPING COUNTRIES AND SOMETIMES HERE IN ATLANTA SO FAMILIES CAN BE HEALTHIER AND SAFER.

I HAVE A MODEL OF THE TOILET HERE.

IT'S A LOT SMALLER N. REAL LIFE IT CAN BE BROKEN INTO DIFFERENT PIECES TO SHIP TO FAR AWAY PLACES OR TO FIT THE NEEDS OF THE FAMILY.

TOILETS ARE A NECESSITY.

THANK YOU FOR BEING HERE.

WE ASKED THE AUDIENCE THE QUESTION.

WHICH OF THE FOLLOWING WAS INVENTED BY AN 11-YEAR-OLD.

HERE'S WHAT YOU SAID.

HILL KNOWS THE CORRECT ANSWER.

FILL US IN.

WHAT IS IT.

>> THE CORRECT ANSWER IS A POPSICLE.

IN 1905 AN 11-YEAR-OLD NAMED FRANK EPPERSON MIXED POWDERED FLAVORING INTO WATER WITH A MIXING STICK.

HE LEFT IT OUT AND THE NEXT MORNING IT HAED FROZEN INTO THE DRINK INSPIRING A POPSICLE >> THAT'S GENIUS.

I DON'T KNOW WHAT I WAS DOING BUT I'M CONFIDENT IT WASN'T THAT COOL.

NOT ONLY WAS ONE OF THE MOST POPULAR TREATS CREATED BY A KID BUT IT WAS DISCOVERED UNEXPECTEDLY.

THAT'S AMAZING.

WE HAVE A QUESTION ABOUT THAT TOPIC.

AUDREY FROM 4-5 ACADEMY IN DECATUR WANTS TO KNOW WHAT OTHER THINGS WERE INVENTED BY ACCIDENT >> A LOT OF THEM.

OTHER EXAMPLES ARE THE SLINKY, SILLY PUTTY AND STICKY NOTES >> THAT GOES TO SHOW NOT ALL ACCIDENTS ARE BAD.

DID YOU HEAR IT, MOM?

WE HAVE QUESTIONS FROM THE AUDIENCE.

RYA FROM MIDTOWN INTERNATIONAL SCHOOL IN ATLANTA WANTS TO KNOW WHAT IS YOUR FAVORITE TOOL TO USE IN THE INVENTION STUDIO.

THIS SEEMS TOUGH.

WHAT'S YOUR FAVORITE?

>> I LIKE THE LASER CUTTER.

YOU CAN CUT ANY SHAPE OR DESIGN YOU WANT OUT OF PRETTY MUCH ANY MATERIAL.

>> FANTASTIC.

WHAT'S YOUR FAVORITE TOOL?

>> HAS TO BE THE 3-D PRINTER.

>> IT IT RATED UNTIL YOU GET WHAT YOU'RE LOOKING FOR.

>> WE HAVE ZANDON FROM BEAVER BROOK.

THEY WANT TO KNOW IF KIDS CAN VISIT?

>> THERE ARE TOURS AROUND GEORGIA TECH AND TO ALL THE PLACES ALL THE TIME.

WE HAVE EXPERIENCED PEOPLE WHO CAN SHOW YOU WHAT TO DO LEER >> I WILL JOIN FOR A TOUR.

WE HAVE MATIAS FROM COMMERCE GEORGIA WANTS TO KNOW IF IT'S LOUD IN THE SPACE?

>> NOT RIGHT NOW.

SOMETIMES IT CAN BE WHEN THE MACHINES ARE ALL RUNNING.

NO WORRIES ABOUT TOO MUCH LOUD NOISE >> IT'S THE SOUND OF PRODUCTIVITY.

MRS.

ROGERS 4th GRADE CLASS.

THEY WANT TO KNOW WHAT INVENTION YOU'RE WORKING ON NOW.

THIS SEEMS SUPER SECRET.

HILL?

>> I WAS WORKING ON SOMETHING THAT DEALS WITH TREMORS IN THE ARMS FOR PARKINSON'S DISEASE.

>> DEV?

>> WE ARE WORKING ON X-RAY VISION INTO THE BACK TO GUIDE NEEDLES SAFELY INTO THE SPINE.

>> MORE NEEDLES.

WE HAVE SEEN COOL MACHINES AT THE INVENTION STUDIO.

YOU DON'T HAVE TO HAVE FANCY EQUIPMENT TO INVENT SOMETHING.

DEV AND HILL WILL DESIGN A CAR USING COMMON HOUSEHOLD MATERIALS.

TO SEE WHICH WILL TRAVEL THE FASTEST.

IN THE WORDS OF THOMAS EDISON TO IMAGINATION.

WHAT DO WE HAVE HERE?

>> SO MANY THINGS ARE GOING ON HERE.

WE HAVE BALLOONS, RUBBER BANDS, CARDBOARD, CDs.

I SEE A LOT OF POSSIBILITIES HERE >> GET YOUR DEVICES READY.

IT'S TIME FOR THE NEXT QUIZ QUESTION.

WHICH OF THE FOLLOWING MACHINES IS AN EXAMPLE OF ADDITIVE MANUFACTURING?

IS IT ONE, VINYL CUTTER.

TWO, EMBROIDERY MACHINE.

THREE, TABLE SAW.

FOUR, THE LATHE.

THAT'S A TOUGH ONE.

NOW WE ARE GOING TO SEE WHAT STUDENTS DO BEST IN THE INVENTION STUDIO.

INVENT.

LET'S CHECK IN WITH JOSH.

TAKE IT AWAY.

>> NOW THAT WE HAVE SEEN WHAT THE MACHINES ARE DOING, WHAT'S THE FIRST STEP IN CREATING SOMETHING NEW?

>> WE'LL USE THE ENGINEERING DESIGN PROCESS.

FIRST WE DEFINE OUR PROBLEM.

THE BIG PROBLEM WE HAVE NOW IS A BEAUTIFUL NEW SPACE WHERE WE HAVE NO SIGN TO ADVERTISE FOR IT.

IN OUR OLD SPACE WE HAD A SIGN WHICH YOU CAN SEE HERE.

THIS SIGN, THE LETTERS ARE TOO BIG.

WE HAVE TO MAKE THEM SMALLER AS ONE OF THE WAYS TO SOLVE THE PROBLEM.

>> ARE THERE OTHER PROBLEMS TO SOLVE?

>> WE HAVE CHANGED THE NAME.

WE NEED A WAY TO MOUNT ONTO THE CURVED CORRUGATED WALL.

>> LET'S MOVE ON TO THE SECOND STEP.

>> SOUNDS GOOD.

>> SOME SOFT THINGS WE SHOULD LOOK AT.

WHAT WE HAVE TO DO NOW IS HAVE A BACKGROUND.

WE HAVE CONNECTIONS IN THE METAL WALL THAT'S HARD TO CONNECT TO.

WHAT INSPIRED US WAS OUR PREVIOUS SIGN DESIGN.

WE DID A GOOD JOB BRANDING THE SPACE.

>> THE OLD SIGN HAS BRIGHT LEDs.

THE NEW BACKGROUND IS DARK.

WITH THE METAL IT HAS ALL THE RIDGES IN IT.

WE MIGHT NEED A SOLID SHEET BEHIND IT.

>> ANOTHER BIG THING IS THE CURVE ON THE WALL.

IT WILL BE A CHALLENGE.

WE NEED TO KEEP THAT.

IF WE CURVE THE BACKGROUND SHEET AROUND THE WALL.

WE DON'T HAVE TO CURVE IT.

THAT'S A FRUSTRATING PROCESS.

>> THERE ARE SHAPES WE CAN USE.

WE DON'T NEED THE UPPER CORNER.

WE HAVE THE WORD FLOWERS ON TOP BUT NOTHING UNDERNEATH.

>> OKAY.

>> ALL OF THE MATERIAL WHICH HELPS US STAY WITHIN OUR BUDGET.

>> THAT FITS WHERE WE NEED IT TO GO.

>> THAT FITS WELL.

>> IT WAS COOL TO SEE YOU AND DAVID GO THROUGH BACKGROUND RESEARCH, SEE WHAT WORKS.

THEN DO SOME SKETCHES AND SPECIFY MORE REQUIREMENTS.

WHAT'S THE NEXT STEP?

>> I'M GOING TO GRAB DREW AND WE'LL FIGURE OUT WHAT MATERIALS TO USE FOR THIS.

>> HEY, JOSH.

I BROUGHT YOU MATERIALS FOR THE SIGN.

>> COOL.

LET'S LOOK AT THESE.

3-D PRINTING.

THIS WOULD BE A COOL OPTION.

WE COULD GET IT TO EXACT DIMENSIONS WE WANTED TO.

WE 3-D PRINT THE CAD MODEL.

>> IT TAKES A LONG TIME AND IT'S EXPENSIVE.

I DON'T KNOW IF THAT'S THE BEST OPTION >> LET'S LOOK AT SOMETHING ELSE.

>> THE NEXT THING I BROUGHT WAS WOOD.

IT'S PRETTY DURABLE.

>> MY ONE CONCERN WITH WOOD IS GETTING INTO THE CURVATURE OF THE WALL.

ONE OF THE THINGS IS EYE CATCHING.

THE NEUTRAL TONE OF THE WOOD MAY NOT BE WHAT WE ARE LOOKING FOR.

>> THE LAST TWO OPTIONS WERE MEDAL.

THIS IS STEEL AND ALUMINUM.

>> WHAT DO YOU THINK ABOUT THE STEEL?

>> IT'S PRETTY HEAVY.

MAYBE IT WILL BE EXPENSIVE AND NOT THE BEST OPTION.

>> WE WON'T BE ABLE TO FINISH IT.

>> IT'S FLEXIBLE, DURABLE AND FLASHY.

>> THE ALUMINUM WILL BE EYE CATCHING.

>> THIS IS A CAD MODEL THAT LETS US DESIGN WHAT IT WILL LOOK LIKE.

WE CAN LASER CUT IT OUT OF CARDBOARD AND SEE WHAT IT LOOKS LIKE BEFORE WE USE EXPENSIVE MATERIALS ON IT.

>> WE'RE GOING TO MAKE A ONE-FOURTH SCALE MODEL OUT OF CARDBOARD BECAUSE IT'S ALSO CHEAPER.

WE CAN SEE WHAT IT WILL LOOK LIKE.

>> WE'RE GOING TO USE THE LASER.

WE COULD DO IT WITH AN EXACT-O KNIFE AS WELL.

>> YOU CAN CUT RIGHT THROUGH IT AND PUT IT ON CARDBOARD.

>> LET'S CUT IT.

>> WE SHOULD HAVE MADE THE Is THICK.

>> WE COULD DO IT IN ALL CAPS.

INVENTION ISN'T A LINEAR PROCESS.

>> REPEATEDLY TRYING TO DO THE SAME THING OVER AND OVER UNTIL IT WORKS.

>> NOW THAT WE HAVE THIS CUT OUTLET'S GLUE THESE ON.

>> YEAH.

>> I COMPLETELY UNDERESTIMATED HOW MANY OF THESE WE WERE GOING TO HAVE.

>> THIS IS A LOT OF PIECES.

LOOKS LIKE WE ARE MISSING SOME.

>> WE HAVE TO CUT MORE OUT.

>> THIS WILL BE SUCH A PAIN OUT OF ALUMINUM.

WE'RE HOT GLUING THEM NOW.

BUT WE ARE GOING TO SCREW THEM IN.

CAN'T USE JUST ONE SCREW.

>> TWO FOR EACH LETTER.

>> THAT'S SO MUCH WORK.

WE HAVE TO FIGURE OUT A DIFFERENT WAY >> WHAT IF INSTEAD -- BECAUSE THIS IS ONE PIECE.

>> WE CAN CUT THIS OUT THROUGH HERE AND BACKLIGHT IT.

>> WE CAN PUT LIGHTS FROM BEHIND IT.

PUT LEDs ON EACH LETTER.

>> ONE STRIP OF LEDs.

IT WILL LOOK CLUTTERED >> LET'S DO THAT.

>> THIS NEW SIGN IS CUTTING AWAY PIECES OF MATERIAL TO CREATE A NEW OBJECT THAT'S CALLED SUBTRACTIVE MANUFACTURING.

LET'S SEE WHAT YOU SAID FOR THE QUIZ QUESTION WHICH WAS, WHICH OF THE FOLLOWING IS AN EXAMPLE OF ADDITIVE MANUFACTURING.

I DON'T KNOW.

WHAT'S THE CORRECT ANSWER?

>> THE CORRECT ANSWER IS THE EMBROIDERY MACHINE.

BECAUSE YOU ARE TAKING THREAD AND ADDING IT TO EXISTING MATERIAL THAT MAKES IT ADDITIVE MANUFACTURING.

WE HAVE A LOT OF SEWING MACHINES FREE FOR STUDENTS TO USE >> IT'S LIKE MATH FOR MATERIALS.

A LOT OF STUDENTS TUNING IN HAVE USED SEWING MACHINES THEMSELVES.

OUT OF CURIOSITY HAVE YOU EVER USED ONE?

>> I HAVE USED JUST ABOUT EVERYTHING IN THE STUDIO.

THAT INCLUDES THE SEWING MACHINE.

>> PERFECT.

DID YOU EMBROIDER THE ETHOS ON YOUR SHIRT THERE?

>> I DIDN'T.

>> I HAD TO ASK.

>> WHEN YOU ARE AVAILABLE AS CAN BE.

>> JOSH V. SHARED ABOUT THE ENGINEERING DESIGN PROCESS.

HOW IMPORTANT IS IT?

>> IT'S SUPER IMPORTANT.

THE START OF EVERY NEW PROJECT WE DO.

IT HELPS US FIND PROBLEMS THAT NEED TO BE SOLVED AND COME UP WITH DIFFERENT SOLUTIONS TO THE PROBLEM.

A LOT OF TIMES THIS ISN'T JUST INVENTING SOMETHING NEW AND USING IT FOR A PURPOSE.

JOSH HAD TO ADJUST HIS DESIGN.

HOW COMMON IS IT TO ENCOUNTER THAT SITUATION WHERE YOU HAVE TO KEEP TWEAKING.

>> THAT'S A PART OF THE PROCESS.

>> IT'S CRITICAL.

>> ABSOLUTELY.

>> IT LOOKS LIKE YOU'RE FIRM ON THE PROTOTYPE.

>> I'M READY TO GO.

IT WILL BE GREAT.

>> DO YOU WANT TO TEST IT OUT?

>> LET'S SEE HOW IT GOES.

>> THAT DIDN'T QUITE WORK OUT HOW I WAS EXPECTING.

I MIGHT HAVE TO MAKE ADJUSTMENTS ON THAT ONE >> WHILE HER CAR IS IN THE SHOP WE HAVE QUESTIONS FROM THE AUDIENCE FOR DEV.

YOU TAKE THESE ON WHILE SHE DOES HER THING.

BRODY MANY MS.

HAYMAN'S CLASS IN KENTUCKY.

IS IT HARD TO PERSEVERE AND KEEP TRYING AFTER YOU FAILED MANY TIMES?

>> IT CAN BE.

WHAT YOU HAVE TO KEEP IN MIND IS NO ONE REACHES SUCCESS ON THE FIRST ATTEMPT.

FAILURE AFTER FAILURE AND LEARNING FROM YOUR MISTAKES UNTIL YOU FINALLY GET THERE.

FOR EXAMPLE, THE ANGRY BIRDS.

WE ALL KNOW IT.

IT TOOK THE DEVELOPERS ALMOST 50 DIFFERENT APPS BEFORE THEY COULD CREATE THAT ONE SUCCESS.

>> INTERESTING.

ONE MORE.

CHRISTIAN FROM KINISAW MOUNTAIN HIGH SCHOOL WANTS TO KNOW HOW YOU GET AN INVENTION OUT THERE.

HOW DO YOU MAKE IT AND PUT IT OUT THERE?

>> FIRST, YOU FIND A SMALL GROUP OF PEOPLE THAT CARE ABOUT YOUR INVENTION.

YOU HAVE TO MAKE SURE IT'S ADDRESSING A NEED, A PROBLEM THEY HAVE.

WHEN YOU MAKE SURE YOUR PRODUCT IS ADDRESSING THEIR NEED PERFECTLY THEY BECOME THE STRONGEST ADVOCATES AND PROMOTERS OF THE PRODUCT.

THEY'LL ADVERTISE IT FOR YOU.

>> TEAM WORK, DREAM WORK.

LET'S TAKE ONE MORE FROM JIMMY AT DUTCH TOWN HIGH SCHOOL.

HIS QUESTION IS HOW LONG DO 3-D PRINTERS USUALLY TAKE?

MY FAVORITE PART, IS THERE A LINE TO WAIT TO USE THEM?

>> 3-D PRINTERS, IT DEPENDS ON HOW BIG THE PART IS.

YOU CAN PRETTY MUCH MAKE ANYTHING IN LESS THAN A DAY FOR SURE.

SOMETIMES IN LESS THAN A FEW HOURS.

YOU CAN SEE HOW MANY 3-D PRINTERS ARE HERE.

THERE ARE HUNDREDS ON CAMPUS FOR STUDENTS TO USE FOR FREE.

SOMETIMES THERE WILL BE A LINE, BUT NOT LIKELY >> NEWS FLASH, THERE IS NOT ONE NOW.

GET IN HERE AND INVENT.

GREAT QUESTION, STUDENTS.

NOW IT'S TIME FOR THE FINAL QUESTION FOR YOU.

HERE IT IS.

WHICH OF THE FOLLOWING INVENTIONS WAS REDESIGNED THOUSANDS OF TIMES BEFORE IT WAS CREATED SUCCESSFULLY.

WAS IT ONE, THE MICROWAVE.

TWO, SUPER-GLUE.

THREE, LIGHTBULBS.

FOUR, ELECTRIC TOOTHBRUSH.

ALL RIGHT.

WE HAVE SEEN THAT FAILURE IS PART OF THE PROCESS.

YOU JUST SPRING BOARD THE KNOWLEDGE INTO SOMETHING BETTER WHICH BRINGS ME TO JOSH.

LET'S SEE IF HE AND THE TEAM HAVE COME UP WITH A FINAL SOLUTION TO THE SIGN PROBLEM.

JOSH?

>> ALL RIGHT.

LET'S GET OUR PIECE IN.

WE'LL PUT THIS IN TO CUT OUT THE FINAL PART.

WE ARE PUTTING IT INTO THE WATER JET WHERE WE CAN CUT THROUGH ALUMINUM.

WE'RE MAKING SURE WE CLAMP IT DOWN NICELY.

NOW WE HAVE IT GOOD TO GO.

>> NOW THAT THE CUT IS DONE LET'S SEE WHAT WE'VE GOT.

>> NICE.

LET'S GET IT FINISHED.

>> JOSH, IT LOOKS AMAZING.

WHAT ARE THE NEXT STEPS?

>> WE'RE ADDING LEDs TO THE BACK SO WE ARE ABLE TO MAKE SURE IT POPS AND NOBODY GLANCES OVER IT.

>> IS THIS THE LIGHT.

>> WE GET ABOUT 20 FEET PER ROLL AND THE LIGHTS ARE CONTROLLED WITH WIRES HERE.

WE HAVE FOUR WIRES HERE.

WE HAVE THE GROUND WIRE AND THE LEAD WIRES.

YOU PUT ELECTRICITY THROUGH AND IT FLOWS THROUGH THE CONDUCTORS.

IT WILL ACTUALLY LIGHT UP EACH LED >> THIS LOOKS EXPOSED.

IS THIS SAFE TO TOUCH?

IT'S COVERED IN AN INSULATOR.

PREVENTS YOU FROM GETTING SHOCKED OR STARTING A FIRE >> BEFORE IT LIGHTS UP YOU NEED A POWER SOUSE.

>> WE HAVE A POWER SUPPLY HERE THAT PLUGS IN LIKE NORMAL.

IT CHANGES THE WALL VOLTAGE WHICH IS HIGH.

>> DO YOU NEED A POWER SOURCE FOR EACH STRIP?

>> WE HAVE A STRIP HERE.

WE ARE ABLE TO SEE.

IT WILL LIGHT IT UP ON TIME.

>> DOES IT CHANGE COLORS?

>> THIS CONTROLLER WE HAVE HERE DISTRIBUTES THE POWER SO WE CAN CHANGE THE COLORS HERE WITH THE THREE WIRES.

>> THAT'S COOL.

NOW WE HAVE GOTTEN THE STRIP MEASURED OUT.

WHAT ARE WE ABOUT TO DO NOW?

>> WE ARE GOING TO SOLDER A CONNECTOR TO THE LED TO LIGHT IT UP.

>> WHAT IS SOLDERING?

>> IT'S WHEN YOU TAKE THIS THIN METAL THAT HAS A RELATIVELY LOW MELTING POINT WHEN IT COMES TO METAL.

MELT IT SO YOU CAN CONNECT TWO OTHER METALS.

NOT STRUCTURALLY, BUT TO CARRY THE CURRENT >> YOU CAN MELT IT.

>> METAL, HOT GLUING.

FOR A CIRCUIT.

>> LET'S DO IT.

>> AWESOME.

>> I'M GOING TO WATCH YOU SO I DON'T HURT ANYBODY.

YOU HAVE THE HOT IRON.

YOU USE IT TO GET THE TWO OTHER METALS WARM.

THEN YOU FEED IN.

>> YOU'RE MELTING THE METAL ON SO IT CONNECTS TOGETHER.

>> NICE.

>> NOW WE SHOULD HAVE A CONNECTION.

>> THE YELLOW TABLE IS CONNECTED.

WE DO IT FOR EACH ONE.

THAT'S GOOD TO GO.

NOW THAT YOU FINISHED SOLDERING THE WIRE AND WE SUPER GLUED THAT ON.

WE HAVE TO TEST OUT THE POWER SOURCE.

>> AWESOME.

LET'S GET IT UP.

>> I HAVE MOUNTED THIS BOARD HERE.

WE HAVE MOUNTING POINTS FOR THE SIGN.

WE HAVE RUN POWER THROUGH THE WALL.

>> PUT IT UP.

>> LET'S GO.

>> THAT'S RIGHT.

THANKS FOR SHOWING US THE WHOLE PROCESS.

>> NO PROBLEM.

ANY TIME.

>> DO YOU WANT TO MAKE SOMETHING ELSE?

>> LET'S GO.

>> THERE IT IS IN ALL ITS GLORY.

THE NEW FLOWERS INVENTION STUDIO SIGN.

THAT WAS COOL.

I LIKED THE WAY IT TURNED OUT.

>> THAT LOOKS INCREDIBLE.

I CAN'T WAIT TO SEE MORE.

WE WANT TO TACKLE A COUPLE MORE QUESTIONS FROM THE FIELD.

ONE QUICK QUESTION BEFORE WE GET BACK TO THE QUIZ.

IS IT HARD INVENTING?

>> YOU JUST HAVE TO GET AT IT REALLY.

THE BEGINNING OF EVERYTHING IS DIFFICULT.

ONCE YOU START DOING THE PROCESS YOU DO IT >> DO YOU THINK IT'S HARD?

>> IT IS HARD.

BUT WHEN YOU HAVE AN IDEA YOU'RE PASSIONATE ABOUT IT'S EXCITING TO PUT IN THE WORK TO MAKE IT SUCCESSFUL >> SO YOU PUSH THROUGH.

NOW TO THE POLL RESULTS.

WE HAVE SEEN IT TAKES A NUMBER OF TRIALS AND ERRORS TO CREATE SOMETHING NEW.

THAT SIGN DIDN'T REQUIRE THOUSANDS BUT SOME DO.

HERE IS THE QUESTION.

WHICH OF THE FOLLOWING INVENTIONS WAS REDESIGNED THOUSANDS OF TIMES BEFORE IT WAS CREATED SUCCESSFULLY.

HMM.

TRICKY, TRICKY.

WHAT'S THE ANSWER, HILL?

>> THE LIGHTBULB.

WE DON'T KNOW THE EXACT NUMBER.

IT IS ESTIMATED IT TOOK THOMAS EDISON AND HIS TEAM 5,000 TO 10,000 DESIGNS BEFORE THEY LAST CREATED A LONG LASTING FULLY FUNCTIONAL LIGHTBULB >> WE HAVE SEEN THE LIGHT.

INVENTING TAKE AS CREATIVE MIND AND PATIENCE.

YOU BOTH HAVE MADE SEVERAL ADJUSTMENTS DURING THE LAST SEGMENT.

DEV, YOUR CAR LOOKS DIFFERENT NOW.

>> I HAD TO USE A DIFFERENT MATERIAL TO MAKE IT MORE STURDY, ADD ANOTHER BALLOON FOR DOUBLE THE THRUST AND PUT IT ON THE BACK SO IT WOULDN'T TOPPLE OVER.

>> THAT'S A LOT OF ADJUSTMENTS.

LET'S SEE IF IT PAID OFF.

LOOK BEHIND ME AT THIS GLORIOUS TROPHY CUP.

THIS IS WHAT YOU'RE WINNING.

IT SAYS ON THE FRONT THAT YOU ARE THE BEST.

I'LL LET YOU KNOW WHEN THE RACE HAS CONCLUDED.

I'LL LET YOU KNOW WHEN TO GET IN POSSESSION.

WAIT FOR MY CUE, PLEASE.

DRIVERS START YOUR ENGINES.

OR SHOULD I SAY FLEX THE RUBBER BANDS AND BALLOONS.

INTERESTING.

TAKES A MOMENT TO GET INFLATED.

ARE YOU GUYS READY?

GIVE ME A NOD.

IN THREE, TWO, ONE, GO.

♪♪ >> I WILL CALL THAT A VICTORY.

THAT WAS ENTERTAINING.

IS THAT THE OUTCOME WE EXPECTED?

>> DEV REALLY HAD IT FROM THE BEGINNING.

>> CAN CONGRATULATIONS.

YOU WIN.

YOU CAN KEEP THE FLAG, TOO >> THE BALLOONS ARE ACTING AS -- IT'S CREATING THRUST AND PROPELLING THE CAR BY PROPELLING THE STREAM OF AIR FROM THE BACK.

BOTH OF THE BALLOONS PRODUCED ENOUGH POWER TO MOVE IT FORWARD.

MAYBE A THIRD ONE WOULD HAVE GOTTEN IT ALL THE WAY >> TO HELP IT ACCELERATE.

IT TOOK OFF.

YOU ARE FEELING ELATED NOW, NOT DEFLATED.

TELL ME ABOUT YOUR DESIGN >> THE IDEA WAS BY ADDING MORE WHEELS I WOULD INCREASE TRACTION AND STABILITY OF THE CAR.

BUT I WOUND THE RUBBER BANDS TOO TIGHT SO WHEN I LET GO IT COULDN'T RELEASE ALL THE WAY.

THERE IS ALWAYS ROOM TO IMPROVE >> IF YOU DIG DEEPER YOU WILL GET TO THE ROOT OF IT.

EXPLAIN THIS BODY STYLE.

>> THE IDEA IS ADDING A WHEEL IN THE FRONT, YOU ARE KEEPING THE FRONT OF THE CAR FROM PUSHING ALONG THE GROUND AND PREVENTING YOUR CAR FROM GOING AS FAST.

THAT WAS A REDESIGN TO THE CAR.

THIS CATCH HELD THE RUBBER BAND IN PLACE MORE.

>> COOL.

I WANTED TO COME UP WITH A NAME FOR THE CARS.

HILL'S WHEELS AND REV FOR DEV.

I FEEL LIKE YOU WON THAT ONE.

>> CONGRATULATIONS.

WHAT IF YOU HAD ONE MORE CHANCE TO REDESIGN.

>> DEFINITELY MORE POWER.

IT DIDN'T MAKE IT ALL THE WAY.

GIVE IT THE EXTRA PUSH >> ARE YOU HAPPY WITH THE WHEELS?

>> I AM.

>> NICE AND FRESH AND MINTY.

WHAT WOULD YOU DO DIFFERENTLY IF YOU HAD ANOTHER REDESIGN?

>> I WOULD MAKE THE BODY OF THE CAR LONGER.

IF YOU HAVE SEEN A RACE CAR, THEY ARE LONG AND FLAT.

THAT DECREASES AIR RESISTANCE TO LET THE CAR GO FASTER.

SO I WOULD MAKE THE BODY LONGER SO IT'S CLOSER TO THE GROUND >> YOU ENGINEERS ARE TRUE PROBLEM SOLVERS.

SHE ALREADY HAS THE SOLUTION.

IT'S IMPRESSIVE TO SEE YOU BOTH DESIGN A CAR QUICKLY WITH SUCH BASIC MATERIALS.

WHAT IF YOU GIVE GEORGIA TECH STUDENTS FREE RANGE OF MATERIALS TO USE?

THIS VIDEO HAS GONE VIRAL WITH OVER 1.6 MILLION VIEWS ON YOUTUBE.

I CAN'T EXPLAIN IT.

TAKE A LOOK >> WE HAVE A BARBIE JEEP.

A LOG SPLITTER ENGINE.

WHAT COULD GO WRONG?

>> WE HAVE THE WHEELS ON.

THIS HAS THE FRONT WHEELS ATTACHED.

ON THIS SEGMENT WE ARE GOING TO TRANSFORM A $6 HARBOR FREIGHT WHEEL INTO SOMETHING THAT I DON'T THINK WILL KILL US WHEN WE TRY TO RIDE THE JEEP.

WE HAVE A THRUST BEARING RIDING ON THE GROUND RACE.

WE CAN BASICALLY SANDWICH THESE GUYS TOGETHER.

BACK HERE WE HAVE THE REAR SPROCKET.

THAT WAS ALREADY THERE.

NOW WE HAVE PROPER HYDRAULIC BRAKES FROM CHINA.

RIGHT DOWN THERE.

YOU CAN BASICALLY PUT IT RIGHT THERE.

>> FILLING UP YOUR CAR?

>> NO.

♪♪ >> THERE'S NOTHING LIKE SEEING YOUR FAVORITE CHILDHOOD TOY GET TECHIFIED DOES THAT COME WITH UNLEADED OR PREMIUM?

>> I HAVE SEEN THEM ON CAMPUS.

I AM JEALOUS TO GET THE WORKING BACK.

>> IT'S PINK.

>> OF COURSE.

WHAT COLOR ELSE WOULD YOU MAKE IT?

>> MAYBE BLUE.

WHAT DID YOU THINK OF IT?

>> IT'S MY THIRD DAY AT GEORGIA TECH AS A FRESHMAN AND I SAW THEM ZOOMING TO CLASS.

THEY OFFERED ME A RIDE.

I WISH I HAD TAKEN THEM UP ON IT.

THEY HAVE TO COME BACK TO CAMPUS.

I WOULD 100% TAKE THEM UP ON IT NOW >> HILL, WHAT WERE YOU THINKING?

>> I DON'T KNOW.

I WAS A FRESHMAN.

I WAS NERVOUS.

THEY ARE PRETTY INTIMIDATING IN THE PINK CAR.

>> ARE THEY?

>> WE'RE INVESTED, TOO.

>> ZOE FROM -- WE TALKED ABOUT YOU HAVE TO PUSH THROUGH.

IT TAKES TIME TO BUILD UP.

HOW LONG HAVE YOU BEEN AN INVENTOR?

>> I DON'T THINK I STARTED UNTIL I CAME TO GEORGIA TECH.

I CAME HERE WANTING TO GO TO MED SCHOOL.

I FELL IN LOVE WITH ALL THE TOOLS AND RESOURCES HERE.

I STARTED WORKING IN THE MACHINE SHOP.

I PICKED UP STUFF ALONG THE WAY.

IT'S BEEN FIVE YEARS COMING >> FIVE YEARS.

TECH IS WHERE IT ALL BEGAN.

YOU PLANTED THE SEED AND THEN THE FLOWERS INVENTION STUDIO CAME.

WHAT ABOUT YOU?

>> A BIG THANK YOU TO MY 8th GRADE SCIENCE TEACHER.

WE DID A PROJECT ON WHAT IT WOULD BE LIKE TO LIVE ON MARS.

I THREW A BEAKER AND A HOT PLATE TO EVAPORATE SALT OUT OF WATER WHICH WOULD BE USED ON MARS IF YOU LIVED THERE.

I CAME TO GEORGIA TECH AND REALIZED THERE WERE SO MANY MACHINES AND INSPIRING PEOPLE TO TAKE IDEAS TO THE NEXT LEVEL >> I LOVE YOUR IDEAS.

THOSE ARE GREAT.

HERE'S A FUN ONE.

MS.

L.B.

'S FOURTH GRADE CLASS AT ALEXANDER 2 MAGNET SCHOOL WANTS TO KNOW IF ANYTHING HAS EVER CAUGHT FIRE.

>> OH, MY GOSH.

>> DEV?

>> YES.

THE FIRST INVENTION I WORKED ON WAS AN ELECTRO CAUTERY PEN.

IT HEATS UP YISHS AND STOPS BLEEDING WHEN DOING THE SURGERIES.

WHEN WE WERE CREATING THE DEVICE, THERE WERE TIMES WHEN THE CIRCUITS WEREN'T AS PERFECT AS WE WANTED THEM TO BE.

WE SET A FEW FIRES BY ACCIDENT.

EVERYONE WAS SAFE.

NO HARM DONE >> IF WE LEARNED ANYTHING, ACCIDENTS HAPPEN.

THEY CAN LEAD TO FRUITFUL RESULTS.

WE'LL TAKE IT.

>> I WORK IN A SMALLER VERSION OF THIS INVENTION STUDIO.

THE LASER CUTTER IS COOL.

SOMETIMES I CAN START FIRES.

THAT'S WHEN WE PULLED THE BIG FIRE EXTINGUISHER OFF THE WALL AND SPRAYED THE LASER CUTTER.

IT WAS A DAY I WON'T FORGET ANY TIME SOON >> SOUNDS DRAMATIC.

YOUR WOOD BECAME KINDLING?

>> JUST ABOUT.

>> ALSO ACCIDENTALLY.

4th GRADERS AT MARTIN ACADEMY, A STEM CERTIFIED SCHOOL.

THEY WANT TO KNOW WHAT ADVICE YOU CAN GIVE A YOUNG STUDENT WANTING TO PURSUE ENGINEERING.

>> THE ADVICE IS DON'T BE AFRAID TO GET YOUR HANDS DIRTY.

NO PROBLEMS ARE TOO SMALL.

IF THERE IS SOMETHING TO MAKE YOUR LIFE EASIER, THAT'S THE PERFECT CHANCE TO INVENT SOMETHING NEW.

DON'T GIVE UP IF YOU FAIL THE FIRST TIME.

THERE ARE PEOPLE AROUND YOU THAT ARE WILLING TO TAKE THE FIRST SPARK OF AN IDEA THAT COULD BE USEFUL.

>> MAKE IT A COLLABORATION.

WHAT ABOUT YOU?

>> THE KEY TO A GREAT INVENTION BIG PROBLEM WHETHER IT'S ONE YOU HAVE OR ONE YOU HAVE IDENTIFIED THAT OTHER PEOPLE SHARE.

IT'S FOCUSING ON THAT PROBLEM.

TRYING TO UNDERSTAND WHY IT EXISTS AND HOW IT CAN SOLVE THIS.

IF YOU UNDERSTAND THE CORE OF THE PROBLEM AND PEOPLE THAT HAVE THE PROBLEM THAT'S GOING TO MOTIVATE YOU TO PERSEVERE THROUGH ALL THE FAILURES UNTIL YOU SUCCEED AND SOLVE IT.

>> KNOW YOUR PROBLEM, FIND THE SOLUTION.

I LOVE IT.

AUDREY FROM MAY RIVER MONTESSORI ASKS IF YOU CAN USE ANYTHING YOU WANT IN THE MAKER SPACE >> YES.

>> SHORT ANSWER, YES.

ANYTHING YOU WANT.

ARE THERE MACHINES THAT YOU CAN TELL THEM ABOUT WE HAVEN'T SEEN TODAY?

>> A CNC IS A ROBOT THAT YOU PUT YOUR PART INSIDE OF THE MACHINE.

IT STARTS CUTTING IT AND MOVING PARTS IN DIFFERENT ANGLES AND GET YOU THE PRODUCT YOU WANT.

IT'S SIMILAR TO 3-D PRINTING.

>> HILL, DO YOU HAVE A GO-TO MACHINE HERE?

>> YEAH.

I REALLY LIKE THE SAWS.

WE HAVE A SAW FOR WHEN YOU ARE CUTTING SOMETHING HORIZONTALLY AND ONE THAT COMES DOWN VERTICALLY.

IT'S LIKE A SAW YOU WOULD USE WITH YOUR HANDS BUT CONTROLLED BY A ROBOT AND HAS MORE POWER.

IT LETS YOU CUT THROUGH BIG PIECES OF MATERIAL REALLY EASILY.

IT'S SUPER COOL >> YOU CAN USE ANYTHING YOU WANT.

>> THERE ARE PEOPLE TO TRAIN TRAIN YOU.

ONCE YOU HAVE THE TRAINING YOU ARE FREE TO GO.

>> IT'S A DREAM BUFFET FOR ENGINEERS.

PERFECT.

WE HAVE A MINUTE LEFT.

LET'S SEE IF WE CAN SQUEEZE THIS ONE IN.

WE HAVE A QUESTION FROM WALNUT GROVE ELEMENTARY IN SWANEE, GEORGIA.

WHAT MATERIALS CAN YOU USE IN THE 3-D PRINTER?

DON'T LOOK AT ME >> JUST ABOUT ANY MATERIAL YOU CAN THINK OF.

THERE ARE EVEN METAL 3-D PRINTERS.

WE HAVE PRINTERS THAT PRINT A LOT OF TYPES OF PLASTICS.

SOME BIOCOMPATIBLE COMPOSITES.

SOME ARE FLEXIBLE.

SOME ARE MORE RIGID.

THERE IS EVEN ONE THAT CAN PUT METAL DOWN AND CENTER IT INTO A METAL 3-D PIECE >> DO YOU HAVE AN ANSWER, HILL?

>> YES.

WE HAVE A REALLY COOL TYPE OF MATERIAL.

THE 3-D PRINTERS USE THEIR OWN MATERIAL.

YOU PUT IN YOUR DESIGN AND THEY BRING MATERIAL, USUALLY A PLASTIC.

WE HAVE COOL PLASTICS CALLED NINJA FLEX.

IF I DON'T THINK ABOUT HOW A NINJA IS FLEXIBLE AND MOVES A LOT, THIS IS REALLY BENDY.

IT'S A CRAZY STEP FORWARD IN TERMS OF MAKING USEFUL PARTS EVEN IF THEY ARE NOT SUPER RIGID >> GOOD TO KNOW.

NINJA.

I LIKE IT.

WE HAVE FINALLY REACHED THE END OF THE PROGRAM TODAY.

I'M SAD IT'S OVER.

I WANT MORE.

THANK YOU FOR YOUR PARTICIPATION.

YOU WERE PHENOMENAL.

YOUR CARS WERE ENTERTAINING TO THE HILT.

OKAY.

THANK YOU TO OUR BRILLIANT INVESTORS, THE FLOWERS INVENTION STUDIO, THE GEORGE W. WOODROUGH SCHOOL OF MECHANICAL ENGINEERING AND OUR FRIENDS AT GEORGIA TECH.

THANKS, LEE.

LIKE I SAID, THE FUN DOESN'T END HERE.

TO EMBARK ON YOUR OWN ENGINEERING DESIGN CHALLENGE CHECK OUT THE RESOURCES ON GPB.ORG/INVENTION.

YOU CAN CATCH AN ENCORE OF THE PROGRAM TONIGHT AT 5:00 ON GPB TV.

WILL YOU TUNE IN?

>> OH, YEAH.

>> THANK YOU FOR TUNING IN FOR OUR INVENTION CRASH COURSE.

WE'LL SEE YOU SOON WITH MORE INNOVATIVE LIVE EXPLORATIONS FROM GPB EDUCATION.

UNTIL NEXT TIME.
