Boxed Reset is based on the original Reset routine by Paul Harris. In this version, 8 cards are chosen by the spectators (4 number cards and 4 face cards.) The face cards are placed into the box and handed to a spectator for safe keeping. Meanwhile the 4 number cards are handled by the magician in a demonstration of sleight of hand.
One at a time the 4 number cards magically turn face-down. In fact at one point the spectator even choses which card goes face-down next and it is done in the most insanely visual way! Lastly the magician turns over all 4 cards to reveal them to in fact be the face cards. When the box is opened the magician removes the 4 number cards to show that all 8 cards have indeed changed places!
