There are twenty coins placed on a table, ten are currently heads and tens are currently tails. You are sitting at the table with a blindfold and hand gloves. You are able to feel where the coins are, but unable to see or feel if they are 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.
How do you create two groups of coins with the same number of heads and tails?
