Is a children's game played in the United Kingdom. The game is played by standing next to a wall and throwing a ball at the ground so that it bounces off the ground, then wall, and returns to the player. Once the first ball is in the air, a second ball is thrown. Balls are thrown and caught in a rotation. The player must perform a sequence of stances while the balls are in flight. If, during one stance, a ball is dropped, the player must go back to the first stance and start again.
