Pink Goo
A few years back when i was 13, a mate of mine came round to my house some time near bonfire night (just after halloween for you yanks) with small tomato sauce style sachets of pink goo, apparantley used to aid lighting bbq's.

Now, the packet said, do not open packet and allow liquid to escape. Only use safely and only for lighting controlled bbq's etc...... whatever.

Our genious idea was this. Lets remove the pink goo from the sachets, infact, lets spread it allover someones doorstep, light it, bang on the door, run away and watch from a distance as the hilarity unfolds with someone trying to stamp out the sticky pink goo with their feet causing trouser fire (and not the good kind). OK, in hindsight, probably not the most sensible and/or mature idea in the world but hey, didnt seem dangerous at the time.

So everything went according to plan, the goo was deployed and aflame, the door was duly banged and we were hidden behind a bush only able to see the top half of the door the way we were crouched. Nobody answered the door, and after about 15 seconds, we could see the flames, few more seconds and the door wasnt a door any more, it was a burning chunk of wood (or upvc, whichever). Hmmm, we guessed nobody was home, ran as far as we could get from the crime scene, and i never dared walk down that street again for fear there would lay a shell of a house (or worse).

Remember this kids, pink goo holds more power than you think, theres a good reason its encased in an uber-safe thin plastic sachet and the 2mm high text warnings saying basically to not try anything that we did
