Project Snapshot

The sail car is one of the simplest car projects, and it provides a great opportunity to learn how wind resistance can be harnessed to propel vehicles.

Test the success of a variety of sails by placing the car in front of a fan, and measuring how far it travels!

Tips and Troubleshooting

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

  • Make sure there's no excessive friction that's hindering the wheels such as excess glue, loose tape, or the wheels pinched around the straw.

  • Try making a bigger sail.

  • Try making the front of the sail pointed or curved so it's more aerodynamic.
