Every day, servicemen and women face real danger. Their very job is to protect us from getting hurt, and that often involves putting themselves and their own bodies in harm's way. It's such a brave thing to do.
Kevlar, the material found inside of the bulletproof vests that police officers and members of the military wear to protect themselves, was invented in 1964. It wasn't, however, intended to save lives. Stephanie Kwolek, a Polish-American chemist, invented the incredibly strong and lightweight material for lightweight tires during the gasoline shortage.
As it happens so often, Kwolek's great invention found an amazing use outside of her original intention, and ended up being the lifesaving material that bulletproof vests are made out of.
But, what does it look like?
When this father-and-son duo asked themselves the same question, they decided to get some answers.
They're no strangers to these experiments, either. They've cut open rubber band balls, mattresses, and even a rattlesnakes's rattle. This dad's instinct to encourage his son's curiosity is truly inspiring. His son is going to learn to ask a lot of questions, and asking questions is the only way to get answers.
But they weren't expecting to learn so much when they took a power saw to a bulletproof vest!
When I saw what was inside those thin, lightweight, lifesaving vests, I was shocked. It doesn't look anything like I thought it would.
