The amazing magic of science!
The lightning bolt is set on the blue rod. The black bar is rubbed over the ridges in the blue bar and behold! The lightning bolt begins to spin as if moved by magical forces. At the command of the magician, the lightning bolt spins in the opposite direction. Only the magician has control over the action of the lightning bolt.
Very easy to do. A classic pocket effect. Made in the USA by FUN Incorporated.
