What is TOUCH THE WALL?

The object is to touch the nearest wall 1/100th faster than your opponent after someone calls out, "Touch the wall!"

One variation includes shouting "7th medal" instead of "touch the wall".

The game is a reference to Michael Phelp's 7th Olympic gold medal victory, in which he won by 1/100th of a second, against opponent Milorad Cavic.
