Treasure hunters in Sweden have discovered something at the bottom of the Blatic Sea, 87 metres below the surface.
What it is is a mystery as of a yet and it'll probably stay that way as the treasure hunters have little funding to actually go down there and check it out. All that people know now is that it's round and has an impact trail following it.
So, what do you think it is? A simple aircraft? A UFO? Cthulhu's frisbee?
