You will need an even number of people for this activity
Hold hands standing in a circle. Move outwards until everyone’s arms are outstretched, but not taut.
Number people alternately around the circle, number 1 and number 2. On a count of three, all the 1s should lean towards the centre of the circle and all the 2s should lean outwards.
Each should counterbalance the other; no no-one should move their feet. Try changing over so that everyone is leaning in the opposite direction.
