    98.62% of the uranium-235 in the Little Boy bomb was blown apart before fission. That leaves 1.38% that actually fissioned. That was 0.7 grams of U-235, about the size of a bb and the weight of a butterfly that destroyed Hiroshima.

      That is wild. I can not imagine how devastating the nukes of today are in comparison.
