Damp Assassins

Sounds like a good way to while away those long hot summer afternoons. A randome water pistol fight with complete strangers. The only problem to me seems to be how would you know who shot who first. I mean normally with water pistol fights everyone just gets soaked in about 5 mintues so the concept of 'kills' seems a little ridiculous. Plus you need a camera phone and most of those aren't water proof as far as I'm aware. Could be an amusing way to bust up your expensive phone though. Anyway if you wanna do it and you live in london and are a chimp the information is here.
