Electronic Magic does not have to be expensive....Mental Die trick is really very nice, but most of them expensive. Here is an affordable version of Mental die, with some better features: Hand the spectator a die and a black box. Ask her to place the die on the table, and cover it with the box, so that nobody can see the top number.. You are facing other side or even blindfolded, and you spell the top number. The black box is removed by the spectator and the die number is correct!!! You can repeat many times.. THE BIG ADVANTAGE comparing with Mental Die. Spectator can hold the Die inside the black box in his hands, behind his back,or place at the table, and cover it with the black box and DO NOT NEED to keep the Die in a Flat surface, like the Mental Die. Well, show a black box and a die, everything can be examined. ask the person to cover everything with his hand, place the die in the box, with any top number. Even if he does't know the number, and cover the black box with his hand, and place it on the back, or hide under a hanky. The magician, even 3 feet away, will say. You chose top number 5 !!!! You receive the black box, the mental die, vibrator, the wireless charger and all cables, and instruction manual.
