Did you know that you can download a FREE, WAY COOL gizmo, our very own Balloon Car Builder? Then, build a real one and see which goes farther, your homemade one or the one on your computer.
- half-gallon milk carton
- balloon
- straws
- 4 spools
- some straight pins
- The milk carton can be the body. Wash out your carton and cut off the top.
- Then, cut it in half the long way.
- Cut a small hole in the middle of one of the short sides of the carton. This is where the balloon goes. You'll probably have to mess around with the size of the hole. If it's too big or too small, there won't be enough force to move the car.
- Put the balloon through this hole, but don't blow it up yet.
- The next thing you do is make holes on each side of the carton for the axles and stick straws though these holes. Make sure they're close to the bottom.
- Then attach the spools to the straws and put pins through the straws to keep the spools on.
- Now, blow up the balloon – don't tie the end – and let your car go!
