Propeller Car

Project Snapshot

Fast and fun, the propeller car is a hands-on lesson in air-powered thrust and inertia. Small, lightweight wheels have less inertia than big ones, which lets the car reach its maximum speed quickly!

​

Just wind it up and watch it race across the floor up to 30'!

Tips and Troubleshooting

If the car isn't going very far, then...

  • Wind up the rubber bands more.

  • Try adding more than 1 rubber band.

  • Make sure the wheels can spin freely.

If the car is out of control when first released, then...

  • If the rubber bands are wound up a lot, then the torque of the propeller may cause the car to spin! Try winding up the rubber bands less, or use fewer rubber bands.
