A wooden box is shown to have 3 buttons and a red light. Show that only one of the buttons can control the light. When the other 2 buttons are pushed nothing happens. Give the box a couple of spins and ask the spectators to push the button they think will cause the light to light. When they press the button the light does not light. Ask them top try again. When they press another button the light still does not light. You press the 3rd button and it lights. Repeat it again and again with different results each time.

It's an electronic marvel of the classic Monte effect!

The new design allows you to open the box to store small items. or accessories for your monte routines. 

Runs on 2 AA batteries not included.
