This huge ball should ideally have a cover to which a string is attached which reaches from the centre to the edge of the parachute.

All the players lie down on the parachute with their feet on the edge and their heads towards the centre. The leader rolls the ball slowly over the bodies right round the circle

The leader controls the ball by shortening or lengthening the string.

The leader then could invite the players to roll over onto their backs, and suggest they close their mouths to avoid swallowing the ball!!

This can be extended by getting the players to sit up as soon as the ball has passed over them, and then to lie down again when the ball approaches them again.
