That's definitely an ingenious idea, Hannah, well done. I like that the ball can keep score, in a way it means that everyone can play and not have to sit out to be the judge, which is sometimes a tough job! Also I like that it might make it more of a reason to play for longer, as you try to beat records. Could it also work if there were more than two teams, I wonder? Great inventing, can't wait to see more from you!!
