The RAF cake experiment... "When Royal Air Force pilots discovered chocolate-coated marshmallow teacakes expanded at high altitudes, they became “the subject of some rather unscientific in-flight experiments” in the 1950s. ⁠ Air crews removed their silver foil packaging and perched them around the cabin for observation: The marshmallows swelled as pressure changed. Eventually, they became too big to eat in one bite. ⁠ ⁠ Many noted that, despite the extreme physical effects, the expansion didn’t compromise the taste. ⁠ ⁠ But the expanding teacakes’ fame was short-lived. After a period of marshmallow fever aboard the V-Bombers departing from Gaydon air base, an explosion put a stop to the fun. ⁠ ⁠ During the summer of 1965, a captain and student pilot forgot they had placed unwrapped teacakes above their instrument panels. When the captain pulled an emergency depressurizing switch during a training mission, the treats erupted. ⁠ ⁠ Shards of chocolate and marshmallow hit the windshield, flight controls, and the men’s uniforms. Shortly thereafter, the RAF put marshmallows on their no-fly list*." ℹ️Dull Men Sharing (*BTW the ban was lifted in 2025)
