Crystal Switch Box
A clear small plastic box that can AUTOMATICALLY switch any small paper!
Endless choices of effects can be done with this box. For example: you ask for paper money from a spectator (let's say a $20 bill), you tell him to fold it and place into the small clear box for safe keeping. The box, which is attached to a ribbon, then hangs around his neck in full view. You write a number on a large pad of paper. You ask the spectator to take the money from the box and to read the serial number of his bill, and amazingly, the number matches your written prediction!
Create almost any mind reading effect with this box!
