No visual aids for this, just use your imagination.
Japanese T.V has a reputation abroad for people doing crazy, often dangerous and very often painful things on gameshows. The show on T.V at the moment is along those lines.
Two teams competing for points. The challenge I just saw had two men sitting in a bath of water, trying to name 7 characters from the famous animation show "Doraemon" while the water was heated to 50 degrees using stones heated red hot over a fire.
The first to do so won 1 point and the first use of the bucket of ice set beside the bath.
Great balls of fire!
