All the chanichim sit in a circle on the floor with their legs out infront of them. Someone stands in the very centre of the circle and all the chanichim that are seated move in so that their feet are pressing on the legs of the person standing in the centre. The person in the centre leans forwards and backwards etc and is supported by all the others' feet. The person standing must stand very straight and must rely on all the others to support him/her.
