Rarely does an effect disturb a spectator's grip on reality, but SUPER HOLE will do just that! Carry a portable hole with you wherever you go!

 

Imagine showing spectators a small black disk, which you claim is an actual hole in reality that lets you penetrate objects. Despite their disbelief, you place it on a card box and proceed to drop a coin inside - through the hole! The spectator can even poke their finger through the hole! Now you open the card box and the coin drops out. Then you remove the hole, showing an unblemished card box!
