At football training just now one of our boys went down badly in his wrist (it was funny as hell watching home go real roll on top of ball fall) but laughter stopped when he burst into tears!
Super Jerry ran across and went to see what the problem was. He wrist was hurting so I took him to the side and poured some magic water over it! Hey Presto his fingers started moving again and he could play.
They never showed me this technique in my first aid refresher course today, but I will have to mention it to the trainer tomorrow as no first aid kit should be with out magic water!!
