It's hard to imagine the Nazis during World War II turning down a weapon that might be too dangerous, but that's exactly what they did to a chemical they code-named "substance N." They tested this chemical chlorine trifluoride, which was discovered in the 1930s, in order to use it in battle against the Allied forces. The substance boiled when exposed to air, exploded when exposed to water, was lethal when inhaled, and emitted hydrofluoric acid when it decomposed. The German soldiers decided that the chemical was too dangerous to have their troops dealing with, even given its incredible power.
