If anyone expects a lump of solid, highly enriched Uranium out of the box, you're in for a disappointment. The product description is quite clear. You get ORE (read 'dirt') so you are lucky if there's one gram of actual Uranium in the box. Off that, only 0.7% is the highly sought U-235. What makes it even sadder, talking about diminishing returns, half of the U-235 naturally vanishes in less than a billion years so, whatever you pay for today, it's going to be less of it tomorrow.
