Professional regurgitator
A professional regurgitator is an entertainer whose act consists of swallowing and regurgitating various unusual objects. The objects may consist of anything from live animals, to light bulbs, billiard balls and kerosene.
Some magicians perform regurgitation as part of their act, but professional regurgitators may perform regurgitation exclusively. In some cases there is debate as to whether demonstrations are true feats of regurgitation or "tricks". For example, Stevie Starr as part of his performance has swallowed an unsolved Rubik's Cube, then regurgitated a solved cube.
