Pineapple - it was something we did on kitchen raids!

All the staff knew what it meant and the campers and that was half the fun of it!

If pineapple was yelled you would stand still with your hands twisted together above your head - and in doing so you became "invisible" and those passing by you could only smell pineapple - I dont know how it started!

We also have sleath which is almost the same - you with your hands together (palms together) and then no one can see, hear or smell you!
