Stand in a circle and get the group to rub their hands together
Then instruct them to rub different body parts
Ask the group if they can start to feel their hands or finger tips tingling
The idea is to focus this energy into a clap around the circle
As the clap comes to you simply send it on round the circle with as much energy and focus as possible
Give the instruction that the clap can be reversed around the circle
Also the clap can be sent across the circle.
Variations:
Try and play this game with your eyes closed, with the idea to not catch anyone out but rather keep the clap going.
(You will need a pair of eyes open to act as adjudicator)
