Coins in Water

Drop a coin in a well and make a wish? What if you want it to land in a particular spot? I would suggest not dropping it straight on-edge. Little variations can add up to some major instabilities and you get some wacky behavior:

But if you drop it flat, with the face parallel to the water's surface? Much more predicable descent. The little eddies help stabilize the coin as it falls through the water.
