When me and my pals were younger, we used to wander around on bonfire night sabotaging other peoples bonfires.
One of my favourite tricks was to secrectly slip a tin of lentil soup in the fire and wander off. A short time later, the tin would explode and molten veg would spray the people round the fire. We also used to chuck in cans of deoderant which was a bit more spectacular.
Not the cleverest move but kids are pretty stupid and I was no exception.
We also used to see who could jump over the biggest section of the bonfire while wearing shell suits!!
