Do you ever do"pick a card trick" to your spectator?
But sometimes you fail to find the card.
So we built up a high-tech system called Mind Detector.
All you have to do is plug-in the sensor,then turn on the switch, stick the sensor to spectator's head.
Now you are ready to go.
Let the spectator memorize the bottom card and cut the card into the middle of the cards.
Dectator scan the cards...then it will....point out that card!!!
Totally freak the spectator's mind!!!
Comes with special cards and detector machine.
You need to prepare 2 of 1.5 volt,AAA Batteries, and one 12volt, 23A Battery.
