In June 1940, British Prime Minister Winston Churchill ordered his new paramilitary unit, the Special Operations Executive, to “set Europe ablaze.” To accomplish this objective, the SOE relied on a military research-and-development department of the United Kingdom’s War Office to invent unique weapons for irregular warfare. Housed in a small underground workshop secluded in the cellars of the London offices of Radio Normandie was the Ministry of Defence 1 (MD1) — but as time went by, everybody began calling it “Churchill’s Toyshop” for its wacky war inventions.
The “toys” designed by MD1 ranged from booby traps and mines to “tank destroyers” and “ship-sinking” devices. Bizarrely, two of its most successful contraptions required one special ingredient: candy.

The first weapon to use candy was the limpet mine, which required combat swimmers to tow a small, bowl-shaped explosive device on their belts and then attach it to ships via magnets. Stuart Macrae, an Armchair Science magazine editor who conducted Mythbusters-like experiments between the 1920s and 1930s, proposed using a popular hard candy called aniseed balls to act as a bomb timer. Macrae reasoned that since hard candy takes minutes to dissolve in our mouths, it would take a similar amount of time to dissolve underwater, allowing a saboteur to escape.
It worked like this: A combat swimmer would plant and arm the limpet mine and begin their evasion. The spring would hit the hard candy, starting the “timer” and preventing detonation. But when the candy dissolved — essentially acting as a bomb fuse — the primer struck the detonator, initiating the explosion. Remarkably, the Allies successfully used them in Singapore during a commando mission known as Operation Jaywick. British and Australian commandos sank or damaged seven Japanese ships with limpet mines and candy fuses.
The hard-candy time fuse and limpet mine combination wasn’t the only food-related device. There was also the Explosive Toffee Apple, which was developed as a sticky bomb. Its design featured a handle attached to a glass ball slathered with either toffee or a glue-covered sock. This sticky substance would cling to a target for a moment before exploding, but it also limited the spread of the explosive residue inside, allowing for a more concentrated detonation. Churchill signed off on the manufacturing, writing, “sticky bomb, make 1 million.” In fact, more than 2.5 million sticky bombs were produced and prominently saw action in Europe, North Africa, and the Pacific.
By the end of World War II, Churchill’s Toyshop developed at least 26 brand-new weapons for the Allies — most of which did not involve candy. The other weaponry included a handheld spigot mortar known as the Projector, Infantry, Anti Tank gun, or PIAT, for use against tanks; a needle-like booby trap called the “AP Switch” that fired a .303 cartridge steel bullet when stepped on; and even a giant bridge-laying tank known as the “Great Eastern” that supported vehicles in river crossings.
