Kevlar is a synthetic fiber whose tensile strength-to-weight ratio is 5 times stronger than that of steel. (So where is Kevlar-man, DC Comics? And would he be Superman's enemy or pal?)
Credit for its discovery goes to Stephanie Kwolek who was working for Dupont in 1965. With gas shortages looming, they were looking for something strong, yet light for making tires.
Later Kevlar would be used in body armor, archery bow strings, bicycle tires, tennis racket strings (John McEnroe would be the perfect pitchman for these babies!), drumheads, wicks for fire dancing (see below), frying pans (substitute for Teflon), and high end Nike sneakers.

So where's the conspiracy, you ask?
An Air Force base around 150 miles from Las Vegas, popularly known as Area 51, is also known far and wide as Intergalactic Parking Zone QW#83. Unfortunately, some aliens do drink one too many fizzy tumquots and/or text while flying. Accidents happen, like the one that crashed in Roswell, N.M. in 1947. Weather balloon, my tentacled foot!

Dude, that better be a soda.
Rumor has is that Kelvar is just one of several things, including Stealth Bombers, that have been reverse engineered from the remains of alien spacecraft.
Are you a fan of alien conspiracies, books, TV, or movies? What technological item do you think might have come from an alien intelligence? Oobleck. Definitely oobleck.
Note: My dear daughter is on day 5 of being sick, and I'm super behind on comments. Spring Break starts tomorrow for both kids and lasts all next week, so there is no relief in sight. I guess that's why this is called the A to Z Challenge, huh?
