Here's another great mind reading trick...

Give your victim a penny and a quarter. Tell them to hold one in each hand but not to let you know which coin is in each hand. Tell them that you will only ask them two questions and you will then know everything you need to know. You guess right every time.

The solution is simple. First ask your victim to multiply the coin in his left hand by two. Watch him/her closely to see how long it takes them to come up with the answer. Wait a few seconds, ask them if they're ready and then ask them to multiply the coin in their right hand by thirteen. Again, you need to see how long it takes them to come up with the answer.

Unless you chose a complete idiot or a super math genious for this trick you should be able to "guess" which coin is in each hand by the amount of time it took them to do the math. If they answered both pretty quickly then you know that the penny is in the right hand because 25x2 is pretty easy to figure out and so is 1x13. If they took a little longer to answer the second question than the first you know that the quarter is in the right hand because it's alot harder to quickly multiply 25x13 than 1x13.

This trick only works once. Twice if your victim is especially impaired.
