Arrowsmith did bob ball in the tinwald hall at the middle of the day. In bob ball there are six players, five people line up behind each other and the other other person stands facing them holding the ball. The person with the ball throws it to the first person in line and that person catches the ball and throws it back. Then they bob down, this repeats until the last person at the back of the line catches the ball, then the back person will run to the front while the other person who started will run to the front of the line. Now it should be that the person who was at the back will be a the spot that they can face the other players, and the other person who started will be a the front of the line. This will repeat until that first person is facing the players again.
