Energy Coins by Matt Mello
Energy Coins is my personal coin bending routine. It consists of two phases, and two coins: one positive and one negative. The performer 'energizes' the negative coin, and the spectator is able to feel that it's heavier. This is one-hundred percent surefire, and they will always feel what you describe. Once energized, the performer slowly picks up both coins and is able to dramatically bend the negative coin with one hand.
