Quietly, in the corner of the Vanishing Inc stand at Blackpool, I witnessed a guy completely vanish a coin with sleeves rolled up. He had the coin in his palm, closed his hand into a fist and when he opened his fingers the coin was gone. I couldn’t figure out where the coin had gone. He then made the coin reappear in a similar manner.
He then showed me the gimmick. Pure genius. I bought one immediately.
