(electrical warbling) carr: we have plutonium, and we have enriched uranium. we have two different types of material that we re going to try and use. plutonium was the better material to use. there was gonna be more of it. you needed less of it to make a bomb, and yet it was harder to detonate. (electrical popping) the initial way to make a bomb was called gun assembly. it was to take two pieces of material and slam them together. (explosion) .causing a critical mass and an explosion. and that was fine if you used highly enriched uranium. but one day, they discovered it won t work with plutonium. the plutonium turned out to be so reactive that you couldn t fire it up a barrel even at 3,000 feet per second. it would fizzle. it would melt down before it got up the barrel.

that you couldn t fire it up a barrel even at 3,000 feet per second. it would fizzle. it would melt down before it got up the barrel. norris: it was a great shock. i mean, maybe this whole plutonium thing had been wasted, hundreds of millions of dollars to develop plutonium. wellerstein: oppenheimer was distraught, and-and los alamos was distraught. rhodes: he considered resigning, he was so depressed, and his friends at the laboratory said, you can t, robert. you ve got to stay and finish this work. it s got to happen. we must do it. and-and reluctantly, he stayed.
