3D3DTremendous block of tungsten.
This is a block of tungsten about the size of one of the larger Harry Potter books (hardcover). The main difference, aside from the lack of character development in the tungsten block, is that the block weighs about as much as some of the people reading the book, 84 pounds. Wow, that's a lot of tungsten!
It came from a scrap metal dealer who reports that it was a collimator vane from a linear accelerator. No further information was forthcoming.
