this ones good, but u need a friend to help
Basically lay out 9 coins or bottle caps in a 3 x 3 square
Get your mate to put a napkin under his bottle/drink
then ask your victim to touch a bottle head as you turn away, while your friend watches he puts his bottle on a specific corner or place on the napkin representing where the victim put the drink.
e.g. say if they take touch the middle coin/cap, then your friends will place his drink in the middle of his napkin, if they touch the top right one, then your friend will put his drink on the top right of his napkin. Make sure you agree the relative positions on the napkin in respect to the coin/cap sq, as to avoid confusion...works everytime
