007. Flipping Coins

There are twenty coins sitting on the table, ten are currently heads and tens are currently tails. 

You are sitting at the table with a blindfold and gloves on. You are able to feel where the coins 

are, but are unable to see or feel if they heads or tails. You must create two sets of coins. Each 

set must have the same number of heads and tails as the other group. You can only move or flip 

the coins, you are unable to determine their current state. How do you create two even groups 

of coins with the same number of heads and tails in each group?
