Abstract

摘要

We examine the physics behind the ‘coin through the rubber’ trick; an impressive demonstration of conjuring, well known to close-up magicians and a favorite of Martin Gardner. The phenomenon is based on an elastically stabilized invagination in a thin sheet of isotropic rubber. We model the process using both Hookean the neo-Hookean descriptions, and identify the conditions for stability. The magic happens when stability is lost.
