A pensioner in Brandenberg, Germany, was casting about with his metal detector last week when it gave an unusual ‘bleep’.
According to German media, it’s cause was what first appeared to be a nondescript but shiny lump of metal.
Then the 64-year-old hobbyist, Bernd Thälmann, gave it a quick test.
It was not magnetic.
This was odd. Bernd had been scouring the terrain around Oranienburg in Brandenberg for some time. He had some experience in what to expect to find.
After bringing it home and leaving it laying around for several days, he and his children began to do some digging on the properties of various metals
What they found caused them to became somewhat anxious.
