- one stone per girl
On a given count, everyone passes their stone to the right. They have to place it on the floor in front of the person on their right. They then pick up the stone that is now in front of them (placed there by the person on their left).
The idea is to settle into a rhythm that goes like this: put-down, pick-up, put-down, pick-up, put-down, pick-up, etc. Things get fun when someone fumbles a stone (the person next to them won't have anything to pass on to their neighbour, and so the stones start to pile up. When the `Stop!' is called, the person with the largest pile of stones in front of them is out).
You can also get the group to gradually speed up, or slow down.
