Wartime
Wednesday: Inventions Birthed during WWII
As the saying goes: “necessity is the mother of invention,”
and war often brings the necessity to create. Most would not be surprised to
learn of the development of new technologies in weapons, computers, planes, and
ships, but did you know the Slinky™ came about during WWII?
In 1943, Naval engineer Richard James was tasked with
figuring out how springs could be used to keep important (and expensive)
equipment safe at sea. During part of his research, he dropped a torsion spring
and watched it “walk” across the floor. (A torsion spring works by twisting and
storing mechanical energy. Take a peek at a mousetrap for an example.) A few
changes were made and by the end of the 20th century over 250
million Slinkies were sold.
What about your hairspray or that non-stick cooking
spray you use? Yep, the aerosol can was invented during the war by Americans
Lyle Goodhue and William Sullivan. It was created as a “bug bomb” to help
thousands of British and American soldiers from malaria-carrying mosquitos
during a campaign in the Philippines.
Do you ladies still wear panty-hose (also known as
nylons)? You can thank the Du Pont Company who invented this stronger-than-silk
material. Devised before the war, it didn’t come into heavy usage until silk
was rationed so air crew could have their parachutes. Nylon became so popular
it became the “go-to” alternative to silk stockings and undergarments.
I love ballpoint pens. They write smoothly and don’t “gunk
up.” Apparently that’s why they journalist and artist Laszlo Biro created the
first commercially successful ballpoint pen. He was fed up by the fountain pen’s
tendency to smudge and grabbed his scientist-brother George to work out the
kinks of an alternative. By 1938, they had a patent and managed to sell 30,000
to the RAF for pilots to use at high altitudes where reservoir pens tended to
leak.
These are just a few of the household items that came into being as a result of WWII. Some of the others? Superglue, freeze-dried coffee, photocopying, and ATM machines.
