Tip: If using the materials shown, the wheels roll better when you stick the toothpick through a cut piece of the drinking straw.
For more fun, scroll to the bottom to see balloon powered cars!
Here are some samples of Rolling Cars. Feel free to use other materials as well! We have metal ramps in the Innovation Center but you can make a ramp out of any materials you choose!
Balloon Powered Cars
Get a balloon and some lego pieces, including those with wheels
Assemble your car and install the engine (Balloon). For best results, blow up the balloon first and then install it
Let go of the balloon and watch it go!
