The magician takes a clear tube and shows it to his audience. It is empty. The magician covers it and adds ONE piece of candy.
Miraculously when the magician uncovers the tube again, the SINGLE piece of candy has MULTIPLIED and filled the ENTIRE container.
As a final kicker, a piece of candy can be pulled out to show it is real, and be eaten! (Candy not included).
A fun, visual effect that is easy to understand, and easy to do.
Audiences love CANDY TUBE.
