Holely by Will Tsai (Supplied with Gimmicks)
We thought it was only possible in cartoons. To take a "hole" and move the hole across a surface of an object. Until Now. Will Tsai has taken that portable hole, and made it a reality.
Take out a playing card or business card, have your spectator sign it, then you punch a hole into one corner. While your spectator is holding firmly onto the card, while you visibly MOVE the hole ACROSS the signature, from one end of the card to the other.
The spectator can now keep the card, moved hole and all.
