You mean like Velcro, Teflon, penicillin, microwave ovens, and vulcanized rubber?
Don’t forget inkjet technology! d;^)
Lexan ?
Microwave ovens... the story I read is that a guy working on a radar setup in 1945 happened to have a chocolate bar in his shirt pocket, and noticed it melting. Totally accidental start of tinkering to create a microwave oven. All because the guy liked chocolate snacks.
Penicillin was discovered by accident in a laboratory sink when someone ate a cantaloupe and placed the rind in the sink with open petri dishes that had bacteria on the growth media.
Then someone a day or so later noticed large areas of the bacterial growth had died upon exposure to the mold growing on the rind.
Thank God no one cleaned up the messy sink!
The same strain of Penicillin mold from that rind is still in use if I am not mistaken.
Many lives were saved because of a messy sink.
Don’t forget ductile iron...my favorite miracle breakthrough.
and Viagra?
