HA HA HA!

HAPPY HALLOWEEN!

HEY, MY COSTUME IS GONNA BE REALLY SCARY.

EVEN TEACHER SUSIE IS GONNA SAY, "AAH!"

>> OK, CLASS.

TIME TO PUT ON YOUR COSTUMES FOR OUR HALLOWEEN PARTY.

LET'S GO.

ARE YOU KIDS READY FOR A HALLOWEEN PARTY?

>> YES!

>> AND IS EVERYONE WEARING THEIR HALLOWEEN COSTUME?

>> YES!

>> FIRST UP, WE HAVE MAY.

>> MEOW.

MEOW, MEOW, MEOW.

I'M A BLACK CAT.

WATCH OUT BECAUSE I'M SNEAKY AND SCARY.

>> OOH, I LIKE YOUR COSTUME, MAY.

>> THANK YOU.

>> OK. NOW MAKE WAY FOR GERALD.

>> OOH!

AH!

LOOK AT ME.

I AM A SCARY, SCARY SKELETON.

AAH!

BOO!

>> OH!

IT'S A SKELETON!

OH... HA HA HA!

AND NOW GET READY FOR SID.

COME ON IN.

>> I AM A SPOOKY BAT, AND I HAVE FANGS TO BITE YOU.

BLAAH!

>> WHOA!

A BAT!

OOH!

>> AND LAST, BUT NOT LEAST, IT'S GABRIELA!

>> I'M A CREEPY, YUCKY, SCARY SPIDER.

BOO!

>> OH, YIKES!

IT'S A S-S-SPIDER!

OH, YOU ARE SCARY.

OOH!

HA HA!

>> SUSIE, DO YOU LIKE MY SUPER SPOOKY HALLOWEEN COSTUME?

>> GABRIELA, I LOVE YOUR SPOOKY COSTUME.

I LOVE EVERYONE'S CREATIVE COSTUMES, AND YOU KNOW WHAT?

I ACTUALLY LIKE SPIDERS.

I THINK THEY'RE AMAZING.

>> REALLY?

>> OH, YES.

SPIDERS ARE ONE OF MY FAVORITE LITTLE CREATURES.

FOLLOW ME, AND I'LL SHOW YOU WHAT I MEAN.

>> OK. >> COME ON.

>> MEOW, MEOW, MEOW.

MEOW, MEOW, MEOW, MEOW, MEOW.

>> WELL, SPIDERS ARE FANTASTIC ENGINEERS.

I MEAN, LOOK AT THESE AMAZING WEBS THEY CAN BUILD.

>> OH, YEAH.

>> WHOA.

SUSIE, HOW DO SPIDERS BUILD THOSE WEBS?

>> GOOD QUESTION.

HERE'S THE AMAZING THING ABOUT SPIDERS.

THEY BUILD WEBS WITH SILK THAT THEY MAKE WITH THEIR OWN BODIES.

DO YOU WANT TO KNOW HOW SPIDERS USE THEIR WEBS?

>> OH, YEAH.

>> WELL, THEY BUILD A STICKY WEB AND WAIT AND WAIT AND WAIT, AND FINALLY, AN INSECT, LIKE A FLY, LANDS ON THE WEB AND GETS STUCK.

>> HUH?

>> THEN WHAT HAPPENS?

>> THEN THE SPIDER SLOWLY CRAWLS OVER THE WEB TOWARD THE FLY, AND THEN... >> AND THEN WHAT?

>> THEN THE SPIDER SUCKS THE INSIDES OF THE FLY OUT AND EATS IT.

>> WHOA!

HA HA HA!

>> NOW REMEMBER, YOU DON'T WANT TO TOUCH SPIDERS OR THEIR WEBS, BUT HOW WOULD YOU LIKE TO TRY BUILDING A WEB JUST LIKE A REAL SPIDER?

>> YEAH.

I WANT TO.

>> OK. YOU CAN BECOME SPIDERS AND TRY BUILDING A GIANT WEB TOGETHER WITH THIS YARN.

>> OH, THAT CAN BE OUR SPIDER SILK.

>> YOU GOT IT.

OK.

FOLLOW ME OUTSIDE AND LET'S SEE WHAT KIND OF WEB YOU CAN BUILD.

IT MIGHT NOT BE SO EASY.

>> OOH, I WANT TO TRY.

I WANT TO DO IT.

>> OOH, HEY, IT'S HALLOWEEN.

YOU CAN PRETEND TO BE A SPIDER AND BUILD A WEB, TOO.

HA!

>> SPIDERS ARE AMAZING ENGINEERS THAT CAN BUILD ALL KINDS OF BEAUTIFUL WEBS.

NOW LET'S PRETEND THAT YOU'RE ALL SPIDERS.

CAN YOU WORK TOGETHER TO BUILD A GIANT WEB?

TAKE THIS BALL OF STRING AND SPREAD IT AROUND THE ROOM.

OUR WEB ISN'T STICKY LIKE A REAL SPIDER WEB, SO WE HAVE TO WRAP IT AROUND THINGS TO MAKE SURE IT DOESN'T FALL APART.

SPIDERS BUILD WEBS TO CATCH INSECTS AND BUGS TO EAT, SO MAKE SURE THE PIECES OF STRING CROSS EACH OTHER SO YOU CAN BUILD A STRONG WEB TO CATCH THINGS, TOO.

EVEN WITH 4 OF YOU WORKING AS A TEAM, IT STILL TAKES A LOT OF WORK TO BUILD A WEB.

ISN'T IT AMAZING THAT SPIDERS WORK ALL BY THEMSELVES TO BUILD THEIR WEBS?

SPIDERS CAN WORK ON THEIR WEBS FOR HOURS, EVEN DAYS, AND IF THE WEB BREAKS, SOME SPIDERS CAN EVEN REBUILD THEIR WEBS OVERNIGHT.

OK. YOU'RE ALL DONE.

LET'S COMPARE AND CONTRAST YOUR WEB TO A REAL SPIDER WEB.

HMM, IT LOOKS LIKE YOUR WEB HAS A LOT MORE SPACES THAN THE REAL WEB.

LET'S SEE IF THESE TOY SPIDERS LIKE YOUR WEB.

HEY, I THINK THEY LIKE IT.

NOW PRETEND THAT YOU'RE ALL SPOOKY SPIDERS AND CRAWL AROUND ON YOUR NEW WEB.

>> HELP!

I'M A FLY STUCK IN THIS GIANT WEB!

OH, NO!

>> OH, NO.

STAY RIGHT THERE, FLY.

I'M A SPIDER, AND I'M GONNA EAT YOU.

>> AAH!

OH, NO!

HA HA HA!

>> HA HA HA!

WELL DONE.

SO WAS IT EASY TO BUILD A SPIDER WEB?

>> NO.

>> I DON'T KNOW HOW SPIDERS DO IT.

WE KEPT GETTING TANGLED AND ALL MESSED UP.

>> WELL, WE SPIDERS ARE AMAZING ENGINEERS, SPOOKY SPIDER ENGINEERS.

>> OK, EVERYBODY.

LET'S CONTINUE OUR HALLOWEEN PARTY.

>> YAY!

>> I'M A SPOOKY, SPOOKY SPIDER.

>> AND I'M SPOOKY, TOO.

MEOW, MEOW, MEOW.

>> SKELETONS ARE SPOOKY AND SCARY, TOO.

BOO!

BOO!

>> I'M A SCARY BAT.

BLAAH!

HEY, SUSIE, HOW WOULD YOU LIKE TO HAVE A BAT COME VISIT YOU?

HA HA HA!

>> ACTUALLY, I'D LOVE TO HAVE YOU VISIT ME.

BATS ARE VERY HELPFUL CREATURES.

>> WHAT?

BATS ARE HELPFUL?

>> ABSOLUTELY.

DID YOU KNOW THAT BATS EAT THOUSANDS OF PESKY MOSQUITOES?

AND THEY EAT LOTS OF FRUIT, SO WHEN THEY FLY AROUND, THEIR DROPPINGS SPREAD SEEDS TO PLANT NEW FLOWERS AND TREES.

>> WHEN YOU SAY DROPPINGS, YOU MEAN POOP?

>> YES.

>> HUH.

WELL, HMM, I GUESS IF I SPREAD SEEDS IN MY POOP SO FLOWERS AND TREES CAN GROW, THEN I AM HELPFUL.

>> YOU SURE ARE, AND CATS, WELL, SCIENTISTS THINK YOU ARE FASCINATING CREATURES BECAUSE YOU CAN DO AMAZING THINGS WITH YOUR BODY, EVEN BLACK CATS.

>> REALLY?

>> OH, YES.

LOOK.

YOU'RE AN AERIAL ACROBAT.

YOUR SPECIAL SKELETON ALLOWS YOU TO LEAP REALLY HIGH IN THE AIR AND LAND SAFELY ON YOUR FEET.

>> COOL.

I DIDN'T KNOW MY CAT SKELETON WAS SO SPECIAL.

>> HEY, WAIT.

WAIT A MINUTE.

SKELETONS ARE SCARY AND SPECIAL?

>> WELL, MR. SKELETON, WITHOUT YOU, WE WOULDN'T HAVE A SKULL TO PROTECT OUR BRAINS OR BONES TO COVER OUR HEART AND LUNGS, AND WE NEED SKELETONS SO WE CAN MOVE, BEND, AND TWIST OUR BODIES.

>> HEY, YOU'RE RIGHT.

SKELETONS ARE SPECIAL.

>> YES.

LET ME SEE YOU ALL MOVE YOUR SKELETONS.

MOVE AND BEND AND TWIST.

ALL RIGHT.

YOU KNOW, YOUR COSTUMES REMIND ME OF A SPECIAL HALLOWEEN SONG.

SID, MAY I BORROW YOUR MICROPHONE?

>> OH, SURE.

HERE YOU GO.

♪ >> YEAH!

SUSIE, THIS IS THE BEST HALLOWEEN PARTY EVER.

>> I AGREE, BUT THERE'S ONE THING THIS PARTY IS MISSING.

>> HUH?

WHAT?

>> WELL, EVERY HALLOWEEN PARTY NEEDS A BIG BATCH OF OOEY, GOOEY, YUCKY, ICKY, GREEN SLIME.

>> OH, THAT'S RIGHT.

>> EW!

SLIME!

>> EH, I DON'T KNOW.

SOUNDS KIND OF MESSY.

>> WHAT?

>> HUH?

>> HA!

I'M JUST KIDDING.

I LOVE SLIME.

>> OK.

IT'S TIME FOR A SPECIAL SLIMY SUPER FAB LAB.

LET'S GO.

>> LET'S GO!

YAY!

>> ♪ SLIMY FAB LAB ♪ >> INVESTIGATE, EXPLORE, DISCOVER.

AHH.

HA HA HA!

>> UM... >> UH...HEY.

SUSIE WAS JUST HERE.

WHERE DID SHE GO?

>> I DON'T KNOW.

>> HELLO!

>> AAH!

>> I AM SUSIE THE MAD SCIENTIST, AND I LOVE TO MAKE SLIME.

BWAH HA HA HA!

IN THIS BOWL, YOU'RE GOING TO ADD ONE CUP OF WATER.

THEN YOU'LL POUR IN ONE CUP OF THIS CORN STARCH.

THEN ADD SOME GREEN PAINT.

MIX IT ALL TOGETHER, AND YOU GET SLIME!

OH.

BWAH HA HA HA!

>> HA HA HA!

>> HEY, SCIENTISTS, IT'S HALLOWEEN.

YOU CAN MAKE ICKY, GOOEY, GREEN SLIME, TOO.

BWAH HA HA HA!

>> OK, SPOOKY SCIENTISTS.

IT'S TIME TO MAKE SLIME.

FIRST, MEASURE ONE CUP OF CORN STARCH AND POUR IT INTO A BOWL.

THEN MEASURE ONE CUP OF WATER AND ADD IT INTO THE BOWL.

THEN ADD SOME GREEN PAINT AND MIX IT ALL UP.

KEEP MIXING AND LOOK AT THAT.

YOU HAVE MADE ICKY, GOOEY, GREEN SLIME.

BWAH HA HA HA!

NOW LET'S INVESTIGATE WHAT HAPPENS WHEN YOU ADD TOO MUCH CORN STARCH.

WHEN YOU COMBINE IT WITH WATER AND GREEN PAINT, IT MAKES THE SLIME LUMPY AND REALLY HARD TO MIX.

NOW LET'S DISCOVER WHAT HAPPENS IF YOU ADD TOO MUCH WATER WITH CORN STARCH AND PAINT.

OOH!

IT MAKES THE SLIME EXTRA GOOEY AND DRIPPY.

NOW LET'S INVESTIGATE THE FIRST BATCH OF SLIME YOU MADE.

WHAT HAPPENS WHEN YOU DROP IT?

WOW!

IT TURNS INTO A LIQUID, AND WHEN YOU PICK IT UP, IT TURNS BACK INTO A SOLID.

HMM, HOW INTERESTING.

WHEN YOU MIX EQUAL PARTS CORN STARCH AND WATER TOGETHER, IT MAKES A SLIME THAT CAN BE BOTH A SOLID AND A LIQUID.

HERE IS A SOLID BALL, AND THEN IT'S A LIQUID.

WOW!

INVESTIGATING WITH SLIME IS ICKY, GOOEY, AND SCIENTIFIC.

BWAH HA HA HA!

OK, HALLOWEEN SCIENTISTS, TELL ME, WHAT DID YOU DISCOVER WHEN YOU MADE SLIME?

>> OH, OH, FIRST, WE FOLLOWED THE DIRECTIONS.

LOOK.

I WROTE THEM DOWN IN MY JOURNAL.

WE PUT IN ONE CUP OF WATER, ONE CUP OF CORN STARCH, AND SOME GREEN PAINT.

THEN WE STIRRED IT ALL TOGETHER, AND, TA-DA, WE MADE SLIME.

>> GREAT JOB.

SO WHAT HAPPENED WITH THESE TWO BOWLS?

>> OH, WELL, WE PUT WAY TOO MUCH WATER IN THAT BOWL OVER THERE AND NOT ENOUGH CORN STARCH, AND THEN NOW IT LOOKS LIKE GREEN SOUP.

>> HA HA HA!

>> AND WE PUT LOTS OF CORN STARCH IN THIS ONE BUT NOT VERY MUCH WATER, AND IT LOOKS LIKE LUMPY, GREEN OATMEAL.

>> WELL, I'M VERY PROUD OF YOU ALL.

YOU MADE SOME NEW DISCOVERIES, JUST LIKE REAL SCIENTISTS.

>> BUT INSTEAD OF REAL SCIENTISTS, WE'RE, LIKE, SPOOKY SCIENTISTS.

>> THAT'S RIGHT, MAY.

ON HALLOWEEN, WE CAN BE WHOEVER WE WANT TO BE.

HEY, LET'S GO ON A SPECIAL HALLOWEEN PARADE AROUND THE NEIGHBORHOOD SO EVERYONE CAN SEE YOUR AMAZING COSTUMES.

>> YEAH!

WELL, I WON'T.

HEY, WAIT.

MAYBE YOU'RE A DENTIST.

OK. WELL, THEN I'LL BRUSH MY TEETH, TOO.

HEY, YOU KNOW--DAAH--THE BEST PART ABOUT HALLOWEEN IS DRESSING UP LIKE A BAT, AND NOW I KNOW THAT BATS CAN BE SPOOKY AND THEY'RE ALSO HELPFUL.

IT'S TOO BAD THAT BATS AND SPIDERS AND BLACK CATS AND SKELETONS CAN'T SPEAK FOR THEMSELVES BECAUSE THEN THEY COULD TELL EVERYONE THAT THEY CAN BE SCARY AND AMAZING, OR MAYBE THERE COULD BE A PLACE THEY COULD SHOW EVERYONE HOW GREAT THEY ARE.

HA HA!

OK.

I'VE GOT IT.

HERE'S MY SUPER-DUPER-OOPER-SCHMOOPER BIG IDEA.

I'M GOING TO INVENT THE NOT-SO-SCARY HAUNTED HOUSE.

INSIDE, THERE WILL BE A ROOM WITH DANCING SKELETONS THAT TELL YOU ALL THE COOL MOVES THEY CAN DO WITH THEIR BONES.

"HI, SID.

CHECK OUT OUR BONES.

WE CAN REALLY MOVE."

ANOTHER ROOM WILL BE FILLED WITH BLACK CATS LEAPING HIGH IN THE AIR.

"COME ON, SID.

MRAAR!

JUMP WITH US.

WHEE!

MRAAR!"

ANOTHER ROOM WILL HAVE SPIDERS BUILDING GIANT WEBS YOU CAN CRAWL ON.

"HEY, SID, COME CLIMB ON OUR WEBS, MAN."

THE LAST ROOM WILL BE A SPECIAL RIDE WHERE YOU CAN CLIMB ON A BAT AND GO FOR A RIDE WHILE HE EATS MOSQUITOES.

"CLIMB ABOARD.

WE'RE EATING MOSQUITOES TODAY.

CHOMP CHOMP.

YUM."

WHOO HOO!

THE NOT-SO-SCARY HAUNTED HOUSE IS SO MUCH FUN.

HA HA!

THAT'S MY SUPER-DUPER-OOPER-SCHMOOPER BIG IDEA.

YAY!

WHOO!

HA HA!

I LOVE MY BAT COSTUME.

HALLOWEEN IS THE BEST HOLIDAY EVER, AND YOU KNOW WHAT?

I JUST DECIDED I'M GONNA SLEEP IN MY BAT COSTUME AND THEN WAKE UP IN THE MORNING AND WEAR IT AGAIN ALL DAY LONG.

HA HA HA!

HMM, I BET YOU CAN'T WAIT TO PUT ON YOUR COSTUME, TOO.

YOU CAN BE A SPIDER, "OOH," A BAT, "AAH!

FLAPPITY FLAPPITY," A CAT, "MEOW," A SUPERHERO, "TA-DA," A HIPPO, "UM, BLOBBITY BLOBBITY BLOBBITY BLOBBITY," A PRINCESS, "HELLO," OR A SUPERHERO HIPPO PRINCESS.

"BLOBBITY BLOBBITY, TA-DA, HELLO."

YOU COULD BE ANYTHING YOU WANT TO BE, JUST LIKE ME--SID THE FLYING BAT SCIENCE KID.

[ECHOES] AND REMEMBER, KEEP ASKING LOTS AND LOTS OF QUESTIONS.

SEE YOU LATER, SCIENTISTS, AND HAPPY HALLOWEEN.

HOO HOO HOO!

HA HA!
