the trick where you give someone a coin and ask them to put it in one hand while your not looking, and you have to guess which hand they have it in? how do you do that flawlessly. i know that one way of knowing is that their subconscious body language will give it away, peoples noses will usual point towards the hand with the coin in., unknowingly

what want to know is how to do it flawlessly, all the strategies and techniques used.

thanks

didnt work on me
haha never mind ill do it eventually
