14. Matches (Image Source: Public Domain)

The match was first created in England, in 1826, when John Walker was stirring a pot of chemicals. He pulled his wooden stir stick out of the pot, and attempted to wipe the glob of chemicals stuck on the end of the table, and was shocked when they ignited. Thus, the idea for strike anywhere matches was born.


15. Saccharin (Image Source: Public Domain)

In the late 1870s at Johns Hopkins University, chemist Constantin Fahlberg was working on researching how coal-tar derivatives interacted with each other, when one of the compounds spilled on his hands. Because it wasn't toxic, he wasn't concerned, and went about his day. Later that night, he went to eat dinner and noticed that everything he touched tasted sweet. The next day, he isolated the compound that had spilled and created saccharin, the artificial sweetener.
Smile at whatever happens.

16. Synthetic Dye (Image Source: Wikimedia Commons)

When William Perkin created the first synthetic dye in 1856, he was actually attempting to create a malaria drug. His failure ultimately turned into a thick, purple sludge, but as he was throwing it out, he realized that the color was popular in the fashion world at the time. He was able to isolate just the pigment, which he named mauve, and create the first artificial dye.


17. Pacemaker (Image Source: Public Domain)

In 1958, while attempting to record electrical pulses with a heart-rhythm recorder, American engineer Wilson Greatbatch accidentally added a component that produced electrical pulses instead of recording them. Immediately realizing he had just simulated a heartbeat, he scrapped his old plan and devoted his time to creating the modern implantable pacemaker.
Smile at whatever happens.

18. Teflon (Image Source: Public Domain)

Roy J. Plunkett discovered Teflon in 1938 while trying to create a better refrigerator. He had combined two gas compounds in a tank for storage, but when he opened it up, found a non-stick substance that was resistant to heat and was chemically inert. Later, it was added to pots and pans, creating the nonstick cooking surfaces we use today.


19. Stainless Steel (Image Source: Public Domain)

Stainless steel was discovered in 1913 while English metallurgist Harry Brearley was working to find a strong enough alloy to make gun barrels that wouldn't erode. He would leave his discarded models in a pile on his workbench that would ultimately rust, though one day he noticed that one of the discarded barrels remained shiny. Upon further inspection, he realized that it wasn't only resistant to rust, but to almost all chemicals. He called his discovery "rustless steel" and it hasn't changed much since then.

20. Vulcanized Rubber (Image Source: Public Domain)

20.jpg


Vulcanized rubber, like that used to make tires, was created by Thomas Goodyear in 1839 when rubber was accidentally mixed with sulfur and left to sit on heat. The heat caused a chemical reaction that turned the soft rubber into a hard, stable, weather resistant material, suitable for use on automobiles.


21. Safety Glass (Image Source: Public Domain)

In 1903, French chemist Edouard Benedictus dropped a glass flask. Much to his surprise, upon impact with the hard floor, the glass shattered, but didn't fall apart. He found out later that the flask had recently been used to hold cellulose nitrate, which created a protective barrier. Today, safety glass used in windshields is treated with a similar solution to make it shatterproof.

saccharin and other artificial sweetener you can find it in nature even in lakes of the polar regions
Round Up is good for developing the mind
