You Do As I Do Plumes by Mr. Magic (5002)

A great effect where a child and yourself put a plume in a empty tube. By turning it 3 times the child every times ends up with the plume upside down while yours is straight up! This can be repeated, of course in combination with a lot of gags untill at the end the child ends up with the plume straight up and yours is upside down.

Comes complete with plumes, tubes and instructions (we do not have English instructions at the moment, German and Dutch are available but the effect is very simple to do…).
