Sit down in pairs (if there are couple among you, they will probably want to sit together).

Every pair gets an ice cube. The goal of the game is to put the ice cube between your mouths and melt it down as fast as you can, using any means and techniques necessary!

Melt the ice faster than anybody else and win! You can set the rewards for first, second and third place. When everybody finishes, you can all start again.
