1) Note how many chemists were involved here. 2) The earliest microwaves (for food and most were industrial sized) were called "radar ranges".
When there is "DIVINE INTERVENTION" in INVENTION
Before you consider Teflon a happy accident, watch Dark Water about the West Virginia town that lived with the consequences of Teflon.
Yes, the first plastic was Bakelite. It was heavily used, but is almost forgotten now.
I think they are all amazing, penicillin I feel has helped millions possibly billions of people, it certainly had helped me when I was a child I would get tonsillitis and chest colds often, one time my fever had gone sky high and I had to be rushed to a doctor, he had no time to waste so with my mother's permission they had to inject penicillin in me to get my fever down, they could not wait for a test if I was allergic to it, so it was a 50|50 chance, fortunately, I was not allergic and my high fever dropped, I still remember that day and the urgency of the situation.

Walker's invention was the first fully self-contained friction match, but that was an evolution, not a revolution.
YOU KNOW I DON'T TRUST YOUR CHANNEL BECAUSE I ONCE LISTENED TO YOU AND I GOT MYSELF HURT REALLY BAD THE INFORMATION YOU'RE GIVING HERE IS GARBAGE
In reference to the Microwave. The story I read is that radar operators during WW2 discovered that placing canned food near the radar transmitter cone caused them to heat up. This observation carried forward by someone to become the "radar range" later renamed microwave.
The ice cream cone kind of makes me think of the " accident " with chocolate and peanut butter.
If vulcanized rubber is used nowadays to produce just about everything, why is there any shortage of baby formula? Surely, Goodyear could solve the problem, right?
John Pemberton wasn't a businessman, he was just a pharmacist. JUST! What ignorance!
Muslims invented everything not christians
Moral of the story: If scientists were perfect we'd still be living in the stone age
