Get everyone to lay on their backs with their legs resting against a wall. Put a ball of your choosing on top of the leg of the person at one end.
The team is tasked with passing the ball without dropping it from one end to the other using only their legs. If they drop the ball, they will have to start again from the beginning.
This activity is a lot of fun, it can be done as one whole team together or in case of larger groups, you can split them into teams that compete which team can finish first.
