The performer picks up a fork on the table, holds it at his fingertips, and proceeds to concentrate. Slowly, eerily, and methodically, the fork begins to bend until it is at a 90 degree angle. So far, nothing original, until you TAKE THAT VERY SAME Fork and display it in its bent position, dropping it on the table.
