“I went “magnetfishing”, this is where you simple tie a strong magnet to a rope and throw it in ponds and pools until you find some metal stuff on the bodom. Mostly you will find junk and bikes and scrapnel. But I live in Belgium, near Ypres where there have been great battles in WWI, and I just threw the magnet across a small pond just outside the city. And believe it or not, I surfaced a grenade.”
