Crystal Switch Box

A clear small plastic box that can switch AUTOMATICALLY any small paper (like memo papers, Money etc...). Endless choices of effects can be done with this box, for example: You take paper money from a spectator from the audience (lets say 20 EUR) you ask him to fold it and place into the small clear box for safe keeping ! The box is then hand on his neck for best view .... You then write on a piece of paper a serial number ...... You ask the spectator to take out the money from the box and to read the cereal number of his bill , the number matches your written prediction !

Create almost any mind reading effect from this box !
