For instance, Thomas Edison had to make more than 1,000 attempts to invent theincandescent light bulb before he finally succeeded. History is replete with numerous otherexamples of people trying, yet failing to make inventions before they eventually succeeded. Yetsome inventions have come about not through hard work but simply by accident. In most cases,when someone unintentionally invented something, the inventor was attempting to createsomething else. For example, in the 1930s, chemist Roy Plunkett was attempting to make a newsubstance that could be used to refrigerate items. He mixed some chemicals together. Then, heput them into a pressurized container and cooled the mixture. By the time his experiment wascomplete, he had a new invention. It was not a new substance that could be used for refrigerationthough. Instead, he had invented Teflon, which is today most commonly used to make nonstickpots and pans. Similarly, decades earlier, John Pemberton was a pharmacist in Atlanta, Georgia.He was attempting to create a tonic that people could use whenever they had headaches. Whilehe was not successful in that endeavor, he managed to invent Coca - Cola, the world - famouscarbonated soft drink.Scientists have also made crucial discoveries by accident when they were conductingexperiments. In 1928, Alexander Fleming discovered penicillin, an antibiotic, in this manner. Hediscovered some mold growing in a dish with some bacteria. He noticed that the bacteria seemedto be avoiding the mold. When he investigated further, he determined some of the many usefulproperties of penicillin, which has saved millions of lives over the past few decades. Likewise, in
