Interesting! Well, I think it is.
Some of the innovations that emerged out of World War II are well-documented, ranging from the microwave to the atomic bomb. But there's one small tool whose WW2 heritage is lesser-known: superglue.
Superglue was first developed by scientists at Eastman Kodak who were trying to design gun sights for the military after they found that some of their failed attempts had other useful properties.
While the adhesive has become known for fixing pottery and clothing, during the Vietnam War, it became life saving. "If somebody had a chest wound or open wound that was bleeding," inventor Harry Coover once told the Kingsport Times-News, "the biggest problem they had was stopping the bleeding so they could get the patient back to the hospital. And the consequence was—many of them bled to death. So the medics used the spray, stopped the bleeding, and were able to get the wounded back to the base hospital. And many, many lives were saved."
