There are 10 standard coins lined up on a table, but each coin is wrapped up such that you can't see which side of the coin is facing up. All you are told is that exactly 8 of the coins have "heads" facing up.

You must separate the coins into two piles such that each pile has the same number of heads facing up. You can turn the coins over, but you cannot see through the wrapping.

Is this possible? If so, how?
