All you need is a brilliant high school student with a knack for nuclear physics, a rebellious streak, and a desire to prove their intellectual superiority. As shown in the 1986 documentary, The Manhattan Project, even a resourceful teen can assemble a nuclear weapon in a matter of weeks if they manage to access the right materials. Just look for someone with the right mix of ambition, genius, and a little disregard for the rules, and you’ll have yourself a homemade nuclear device in no time!
