43 strip holders? Piece of p*ss!
Course when I was at Henty House (FSO 59/1982) we only had plastic strip holders....
I tried to annoy a particularly crotchety Center Supervisor one boring morning by making a gun out of strip holders. Rubber bands for ammo. Strip holders on their ends for targets. He put up with it for about half an hour, but instead of the expected explosion he asked me for a turn....
A sports bag full of paper helicopters was a good sight off the roof also.
