America's clandestine operators developed some pretty diabolical weapons to help inflict death and destruction behind enemy lines in World War II. And in the fight against the Japanese occupation of China, the plans got downright dastardly.
In 1942, the Office of Strategic Services began working with Ukraine-born George Kistiakowsky who was a physical chemistry professor at Harvard University and developed an innovated explosive powder designed specifically for guerrilla warfare.
Kistiakowsky secretly created "HMX" powder, or "nitroamine high-explosive" that could be mixed in with regular baking flour and make various inconspicuous-looking baked goods.
Kistiakowsky managed to perfectly combine the HMX compound with a popular pancake mix and package the new weapon into ordinary flour bags that could be smuggled through the numerous Japanese checkpoints and delivered right into the Chinese fighters' hands.
The explosive looked no different than regular pancake mix and if a suspicious Japanese soldier forced the smuggle to whip up a batch and eat them, there would be no ill effects except for a bit of a stomach ache.
Once the weaponized flour was in the hands of the Chinese allied fighters, muffins were baked from the Aunt Jemima pancake mix and a blasting cap was added to complete the destructive war device.
It's reported that approximately 15 tons of pancake mix was imported and was never detected by Japanese forces.
