1942: The Dambuster Marbles

“Sir Barnes Neville Wallis (1887–1979) is best known for inventing the bouncing bomb used by the RAF in the “Dambusters” raid during World War II. Early in 1942, Wallis began experimenting with skipping the marbles above over water tanks in his garden. His idea was that a bomb could skip over the surface of water and sink directly next to a dam wall as a depth charge”
