With this black billet box, you can secretly and easily switch the contents for something completely different. The method can be used for a wide variety of routines – especially within mentalism.
- You can collect drawings or words from the audience in the box, let a spectator pick one, and read their thoughts.
- You can place a prediction inside the box and let the audience freely choose between two options – and you can be 100% certain that your prediction will match.
- Or you can put a blank slip of paper in the box along with a marker, and when the box is opened, something has mysteriously been written on the paper.
The black switching box measures 24 x 15 x 17 cm and has a slot at the top. There is nothing to see inside, either before or after the switch, which is triggered by pressing one of the screws on the back.
