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.
