Players form a circle with a 20m radius, use 1 ball per 5 players. Same amount of players as there are balls start in the middle, all balls start on the outside of the circle
(A) handballs to the feet of (B) who is front and square to (A) and calling for the ball, (A) then sprints into the centre to where (B) is
(B) crumbs by taking the ball just after it hits the ground, then handballs on-the-up to (C) before sprinting out of the centre to where (C) is
(B) handballs on-the-full to (C), not at their feet
(C) handballs to the feet of (A) who replaced (B) in the middle, then sprints after their handball into the centre
(A) gathers the half-volley then handballs on-the-up to (D) before sprinting out of the centre
(A) handballs on-the-full to (D), not at their feet
This process continues with all balls simultaneously around the circle
