I came across a TikTok video about a Plutonium core designed as the third nuclear bomb in WWII that was not needed. Instead, it was kept at Los Alamos Laboratory for experimentation. It seems some scientists liked to "play" with the core and accidentally initiated a fission reaction on at least two occasions but were able to interrupt the reaction before the whole thing went boom. One of the scientists called his tempt of fate "tickling the tail of the dragon". In 1964, the dragon awoke long enough to kill him. He was not the first. It seems remarkable to me that they did not wipe Los Alamos from the map. VIDEO
