This was the late 1950s when children could go to the corner shop and buy individual fireworks for pennies, and very few people owned a car: There was a lady who lived near us who, whenever us children were playing near her house, would come out and shout at us and threaten to "call the police on you lot", even though we weren't doing anything wrong or harmful. We only knew her as Hiawatha! One evening, early November, we were collecting wood for the huge bonfire the grown ups built for us on the field for Bonfire Night and, as usual, Hiawatha came out shouting at us and threatening to call the police. One of the older boys went to the corner shop and bought 2 bangers for 2d each. We unscrewed the petrol cap on Hiawatha's car, lit the banger and dropped it in the tank! Because we were stupid, we took the safety precaution of sticking our fingers in our ears, whilst standing close by so that we could witness the effect! Luckily, the banger went out, causing no damage and Hiawatha saw us hanging around her car and chased us all away.
63 years later, I still wake up in a cold sweat thinking of what could have been!
