Did you ever want to be David Copperfield and cut yourself in half and walk down the street and scare people? Well, now you can at a fraction of the cost. (And time to build the illusion) Give someone a laser pen and ask if they saw the Copperfield special. You did? I can do that. Pick up a board "for protection" and hand someone a laser pen and turn it on. Ask them to slice you across the waist to be careful not to hit anyone else. The laser cuts through you and the board and the audience slowly sees your top half SLIDE OFF OF THE BOTTOM HALF!
