An Eggs-traordinary Eggs-planation

A good “sucker” effect, in which a trick is apparently explained but finishes with a surprise.

Performer shows a handkerchief and tells audience he will cause it to disappear in a mysterious manner.

He rolls it up in his hands and pretends to put it into his left hand. He then places his right hand in his right trouser's pocket. Audience believes that he placed the handkerchief in his right trouser's pocket. Magician, however, opens his left hand and shows that handkerchief is really in his hand. He rolls up handkerchief again, and this time it changes into an egg.

Saying that he will explain the trick so that the spectators can do it, too, Magician shows that the egg is just a hollow celluloid egg with a hole in it into which he tucked the handkerchief. He pulls out the handkerchief and repeats the experiment, changing the handkerchief to an egg again. Performer then explains that in case anyone is suspicious of the egg, all that has to be done is to break it.

He does this and allows the contents of the egg to fall into a glass, thus showing the egg to be a real one.
