Make your very own A-Bomb.

[Sethomas]

In short, it would work. Dumbass. The complicated technology's not in making the bomb, it's in refining the materials.

There's nothing complicated about an isotope centrifuge. It's just really expensive. If you think it would work, you obviously haven't looked into Heisenberg's contribution to the development of the bomb. He miscalculated the critical core radius by a power of ten in the 1940s, an error without which Germany almost certainly would have won the war.

If you struck a uranium hammer onto a uranium anvil, what would happen is both surfaces would smear out. Heavy metals are generally quite malleable, so they would prefer to reshape towards an open direction rather than undergo fision. That's why nuclear cores have to be perfectly spherical and apply uniform pressure at the time of detonation.

Hence, it would almost be possible to create the kind of bomb described in that page if the anvil were a spheroid encased in a berylium shell, but the necessary force of impact would still be well above the threshold of human strength.

Dumbass.
