all the chanichim stand in a circle looking at the floor. when the madrich says "go" all the chanichim must open their mouths and after a few seconds/few minutes a drop of saliva will fall from some people's mouths. the aim of the game is to not let a drop of spit leave your mouth but you must stand with your mouth open the entire time, not use your tongue or hands to stop a drop from falling. the last person without a drop of saliva having left their mouth wins.
