The rules of Lie Detector Prank are quite simple:
- you will see a special device on the screen with a button
- when you press this button a sound and animation will be played
- then your friend should say something
- then look at the middle light, when you tilt your phone left or right it changes colors to red or green. Green means the truth, red means the lie!
- when you know your friend lies tilt your phone to the right
- when you know your firend says the truth tilt your phone to the left
- wait a few seconds and that''s it! You can ashame your friend!:)
