The vibration causes this propeller to rotate. Rapid back and forth movements of the round wood on the ribbed wood create a vibration that, if done evenly, creates a rotating propeller. The fun part is that by keeping your thumb or finger in the right place, you can make the propeller rotate to the left or to the right! It is always a success with young and old, if you demonstrate it with a lot of acting..."stand on your left leg, then it turns to the left...stand on your right leg, then it turns to the right..." then invite the "spectator" to imitate it... great hilarity! Just try it!!! (don't tell them that the left/right only depends on the position of your thumb/finger) The tickling sensation in the hands that is created is also fun.
