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!

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.
