A very funny Do-As-I-Do routine with two bottles and two tubes and an assisting spectator. The spectator follows every move you do but at the end their bottle is always upside down!
The bottle is placed inside the tube and the tube is held between the hands and turned over a couple of times. When you raise your tube your bottle is always right side up. The spectator does the same motions but their bottle is always upside down!
This effect can be repeated several times much to the delight of the audience.
As a final effect your bottle is turned over automatically within the tube with unbelievable speed.
Great comedy potential!
