Went looking for mushrooms in the woods with some friends. A few meters off a trail we found a rusty metal pipe sticking out of the ground. Looked like someone threw some chemical waste out. We tried to open it, to pull it out, we put a stick in (I get sweaty palms writing this down right now) and smelled the strange liquid. It didn’t work so we went home. One friend send the location to the local waste authority. They called a day later, it was a phosphorus bomb dropped by the British during WW2, it was still active and had to be defused. Fuck me! This was not deep in the woods, people walked by in plain sight for decades.
