HEY, DESIGN SQUAD NATION, HERE'S A BUILD YOU CAN TRY AT HOME.

IT'S CALLED RUBBER BAND CAR.

START WITH THE CARDBOARD.

HERE'S A REALLY IMPORTANT STEP.

THE CARDBOARD HAS TO GO TO THE SIDE.

AND HERE'S A LITTLE TRICK-- I'M GONNA STICK THIS PENCIL THROUGH HERE SO MY AXLE SPINS REALLY WELL.

AND THAT'S GONNA MAKE MY CAR BEAT JUDY'S.

WHATEVER.

START YOUR ENGINES.

[BOTH IMITATING LOUD ENGINES, JUDY COUGHS] 2, 1.

HA HA!

WHOO!

NOW IT'S YOUR TURN TO MAKE YOUR OWN RUBBER BAND CAR.

TAKE A PICTURE OR SKETCH OF YOUR CREATION AND SEND IT TO THE "DESIGN SQUAD NATION" WEBSITE.
