Wringer (magic trick)
The Wringer is a stage magic trick. The magician places his assistant into a large box with a set of rollers in the front. The magician turns a crank, and the assistant emerges through the rollers, now flat as a pancake. The magician then opens the front of the box, revealing it to be empty. The magician may later restore the assistant, though this is not required. This trick can also be performed with small animals, such as ducks or rabbits.
Magician C.J. Johnson often performs this trick.
