An easy to do magic trick you can perform with your device.
A spectator chooses a number between 1-60. A set of numbers is shown on the device, and the spectators says if her number is visible or not. This is repeated a few more times.
When you wave your hand, the device suddenly shows the selected number. The spectator never said what her number was, yet the number shown is the correct selection.
You can even tell the spectator what her number was, instead of showing it on the device.
Can be immediately repeated.
Works in any language. Instructions are in English.
