This Christmas, Sonny Cater (aged seven) received a curious gift from Santa Claus: a National Geographic metal detector, worth 36 euros. Soon after, while exploring some fields near his home, in Norfolk (England) with his brand new metal detector, Carter found a metal capsule wrapped in caked mud.
The boy took it home and when his father Jem Carter, 37, washed it, he began to suspect that this metallic device it could be a dangerous thing and immediately contacted his wife's father, Steve Wood, who was a former gunsmith for the RAF (Royal Air Force).
Mr. Wood advised them to call the police immediately and to put the gadget in a bucket of cold water, a precautionary measure in the event of a German phosphorous bomb.
The authorities dispatched a team of bomb experts who determined that the device was a british practice bomb weight of 4 kilograms manufactured during the WWII.
Finally, the artifact was removed so that the experts could proceed to its safe disposal. After the initial scare, Sonny's mother pointed out that at least the incident had helped prove that her son's Christmas gift was working properly.
