HANDBALLKOPFBALL

Use handball or soccer goals on each side of a rectangular pitch. Use brooms. Adjust pitch size depending on number of players, think about 30-40m for 4vs4. Played with 1 volleyball. 

Rules: 

Volleyball carrier must not move (like ultimate). No contact on carrier, but failure to pass on a count to three forces a turnover. Volleyball on floor is a turnover. Teams can pass around by throwing the volleyball, but goals can only be scored with a header. Passing to yourself is not allowed. 

Scoring from headers is tricky, hence the need for precise passing and positioning.
