TENNIS BALLS IN SEA WAR
The United Kingdom’s entire wartime output of 23 million tennis balls helped to defeat the German magnetic mine. This was revealed by the Henley Tyre and Rubber Company, one of Britain's leading rubber manufacturers. Minesweepers towed about 500 yards of electric cable which passed a powerful electric current into the sea, exploding magnetic mines in the area. Cables made from tennis balls packed tightly one against the other were found to be sufficiently buoyant to keep the electric wires on the surface.
