The Mystery Stick is mysterious indeed! Vibrations produced by rubbing the notches in the stick can be controlled to make a second, smaller stick attached to the end twist clockwise or counterclockwise, creating a bizarre, fascinating, and, dare we say it, mysterious, effect. Have fun with your friends by making it appear that the small stick changes direction in response to a spoken word or phrase.
