Transpo spot

The performer shows two matchboxes. One box has three different colored spots on one side of its tray while the other one does not have any spots on either side. The trays are opened to show that the boxes are absolutely empty. A spectator is requested to place her on the table perpendicularly like a wall. The spotted box is placed on the right side of her hand and the other one on the left. The performer states that it is very important that both the boxes must be on the same straight line. He then states that the spots will leave its matchbox, penetrate through her hand and attach to the other matchbox. He then closes the trays of both the boxes simultaneously. The boxes are removes to prove that the magical transfer has taken place.
