This is a mental magic app.
Read someone’s mind or show how you can influence or predict the choices he will make.
(LINK TO DETAILED INSTRUCTIONS BELOW)
Use this app to take a picture and tell the participant he is going to have to choose one of four items that are on the picture. You secretly circle or mark one of the objects and put the phone down flat on its screen.
The spectator now makes a choice. He announces which item he is thinking of. You hand him the phone, he turns it over: you did circle the object before he even decided to choose it! You immediately repeat the experiment with 4 different objects and succeed again.
This one of the many presentations you can use.
