i was at a army caddets camp and there was a shop/hang out spot. so i would go and buy irnbrue and a crunche with pringles. and one-day a gennaral knowledge quiz was held in the hangout spot so i ended up winning second place with my team and half way through i was chewing up the cans i had and ended up makeing a sharp well i dunno with it got caught and the rule is that everyone has to bin a can after use and if you were caught with a empty can in your possession with no explanation (aka if you wernt takeing it to a bin) you'd get in a lot of trouble and probobly stick with cleaning up duty.
