Finger Surfboard

thingiverse

This is a finger sized surfboard. It can be used in the water, but it is more fun to play with it while riding in a car. With the window down, you can surf the wind! Put a string, or some kind of strap, down through the hole and knot it - this will keep it from flying away. Then tie the other end of the string around your wrist. The surfing is ready to start!
