Here's what you need to make your Rubber Band Car:
Make the body
Hold your cardboard so the corrugations (tubes) run side to side, not up and down.
Make the body (cont'd )
Make the axle
Slide the skewer straight through one of the corrugations so it crosses the middle of the notch.
Make the axle (cont'd )
Make sure the axle sticks out the same amount on each side of the body.
Make the wheels
Make the wheels (cont'd )
Create a "catch"
Attach the power source
Power your car
Let go of the axle, and watch your car zoom away!
Did you know?
When you wind up your rubber band around the axle, you’re giving it something called potential energy, meaning energy that’s stored to use later. When you let go, the axle spins and turns the potential energy into kinetic energy, or motion. The more you wind up the rubber band, the more energy it stores, and the faster and longer it goes!
