Everyone but one person is standing on a chair in a circle. The extra person points to a chair and and slowly takes it away so that the chanichim are forced to stand on each others chairs and support each other to prevent anyone falling down (eg into a crocodile pit). The person taking away the chair is working with the chanichim, not against them. This is repeated untill the chanichim clearly will not be able to support each other any longer if another chair is taken away. The idea is to see how few chairs everyone can stand on.
