Magicians have protested against a new exhibit in a Wisconsin museum giving away the secret to one of illusionist Harry Houdini’s most famous tricks. The exhibit at the Outagamie Museum in Appleton, Wisconsin shows how Houdini performed his Metamorphosis trick.

In the illusion Houdini--supposedly handcuffed in a sack and locked in a trunk--miraculously switched places with

an assistant on the outside.

Some members of the Magic Circle have been angered by the museum’s decision. Illusionist David Copperfield and magical duo Penn and Teller have reportedly expressed their disapproval, along with lesser-known practitio -ners ofthecraft. 'This is a very, very passionate thing that magicians feel about,’ said Ronald 'Rondini' Lindberg. 'What the museum is doing is wrong.’

However, curator Kimberley Louagie defended the museum’s

actions. 'We didn’t feel like we were exposing anything, because this information is readily available,’ she said. 'By telling people how this trick works, we’re giving people a deeper meaning of Houdini.’

The Houdini exhibit features 38 artefacts, 190 documents and 'hands-on' displays that include handcuffs, lockpicks, a straitjacket and ajail cell.

Houdini was born Ehrich Weiss in 1874 in Budapest, Hungary. His family moved to Appleton when he was four and stayed four years. He died on 31 October 1926 of a ruptured appendix.

Illusions

The part of the exhibit that shows how tricks are actually performed is in a backstage area. The entrance bears a sign warning visitors not to enter if they do not want to know how Houdini achieved his baffling illusions.

The Metamorphosis trick uses a device known as the substitution trunk, which has a secret panel that allows its occupant to sneak out. Having extricated himself from the sack in which he was tied, Houdini would climb out of the hidden door and crouch behind a

curtain lifted by his assistant.

The magician and his assistant would then change places, Houdini appearing behind the curtain as the assistant disappeared into the box. The assistant would then emerge from the box and sack wearing a different costume.
