One US Marine fighter squadron made their own ice cream during World War II

The Night Witches

During World War II, one of the most effective Soviet bombing units flew wooden crop dusters that maxed out at 94 mph. They had no radios, no radar, and no parachutes. And the pilots? Young Soviet women, mostly in their teens and early twenties. The Germans called them Nachthexen—Night Witches. Shooting one down earned a Nazi soldier an Iron Cross, one of the highest military honors. However, for decades, most of the world forgot they existed. In this video, we trace how the Night Witches became one of the most feared units of WWII—and why their story nearly disappeared from history.

Comic books were used as a form of government propaganda in World War II

The government recognized that comic books were widely read by servicemen (with nearly half deeming themselves regular readers) and by people around the world, making it a perfect vehicle for its antifascist, pro-American message. In addition, the medium was rather crude, allowing for what historian Paul Hirsch called "incredibly aggressive propaganda."

Different types of ice link water molecules together in unique shapes

The ice used to cool drinks—Iₕ—is composed of H₂O molecules arranged in hexagonal structures. This structure forms as ice expands during freezing, providing additional space between molecules, lowering the overall density, and allowing it to float in water. Under sufficient pressure, this spacing can collapse in many ways, creating new forms of ice.

Metal fragments can create glowing rings when sand chips them off helicopter blades

The Kopp-Etchells effect—named after two soldiers who died in action in Afghanistan—may occur when kicked-up material shaves off fragments from a helicopter blade's abrasion strip. Due to a property called pyrophoricity, the fragments react with air and ignite, producing halos.
