6. Vulcanized Rubber
Thomas Goodyear accidentally spilled sulfur, lead, and rubber on the stove for a long time. This gave rise to an extremely helpful product named vulcanized rubber. This is used to make tires and shoes.
7. Stainless Steel
Harry Brearly was ordered to make a rust-free gun barrel for the soldiers. He experimented with different varieties of metals and studied them thoroughly. He found out that 13% of chromium steel had not corroded over several months. And this is how stainless steel came into existence
Teflon was invented completely by accident. Dr. Roy Plunkett was trying to make a better coolant gas in refrigerators for DuPont. He left a batch of gas overnight and observed that it had polymerized very rapidly. It left behind a slippery wax-like solid with exceptional properties. Now, Teflon is used as a coating over non-stick pans & for dentistry.
9. Artificial Sweetener
Saccharin was discovered by Constantin Fahlberg. He was working with a coal tar derivative benzoic sulfimide. After a long day at work, he went home. When he sat down for dinner without washing his hands he found out a sweet taste. He later compared the taste with the compound and gave it a trivial name- Saccharin.
10. Post-it notes
In 1968 a scientist ar 3M company created a very weak adhesive that would peel of when removed from any surface. The pun lies in the fact that he was trying to create a super strong glue. Later another scientist found out that the adhesive gets off the paper without leaving any mark.
