The Petard Pinch

Starting in February of 1942, the codebreakers at Bletchley Park faced a serious problem: They couldn't break the German Army's latest "M4" flavor of the Enigma. Although work continued on breaking this new version of the code, the outlook was grim. But on October 30, HMS Petard and three other Royal Navy destroyers attacked the German U-boat U-559, eventually forcing it to surface and the German crew to abandon ship. While the Germans swam away from their ruined U-boat, three British seamen left Petard and swam to the sinking U-559. What they pinched from the wreck saved tens of thousands of lives for the Allies.

Made for an exhibit at Bletchley Park, here's a video explaining and commemorating what became known as "The Petard Pinch," an act of wartime bravery that led to the breaking of the M4 Enigma.

The art of vanishing fore-edge painting—hiding delicate images on the front edges of gilded books—dates back to about 1660. Today, British artist Martin Frost is the last remaining commercial fore-edge painter in the world. He works primarily on antique books, crafting scenes from nature, domestic life, mythology, and Harry Potter. Great Big Story recently caught up with him in his studio to learn more about his disappearing art. Learn more in the video below.

Kenny Sing's handmade pottery is impossibly precise. He uses design software and paper stencils to cut sharp geometric patterns into his handmade pots. But it's when the pots start spinning that they turn into something truly unique. See more Turn Studio work on Instagram
