This was a gift given to all attendees of the FISM magic convention in Lausanne, Switzerland in 1991. The novelty is that when a coin is dropped through the slit in the top of the box, it immediately vanishes, although it can still be heard rattling around in the interior which apparently contains no more than a top hat floating in mid-air. This is a well made puzzling illusion. US Patent No. 4967953. Created by Tenyo. Made in Japan.
