But this experiment turned out to be the high melting point lubricant now consistently applied to all non-stick pans. Teflon was first used in military applications and is now famously applied to cookware around the world. The psychoactive properties of the acid were discovered almost by accident by Dr.
Albert Hofmann, a research chemist working for the Sandoz Company, in Hofmann had been synthesising LSD , and some crystals of the substance made contact with his fingertips and were absorbed through his skin. In , British chemist John Walker discovered what are now matchsticks when he accidentally scraped a stick coated in chemicals across his hearth and found that it caught fire, and the idea struck him to convert these to proper matchsticks.
In , Chemist Edward Benedictus was working in his lab when he accidentally knocked over a flask. However, when Benedictus looked down, he noticed that rather than breaking into a million little pieces, the glassware had actually just cracked slightly while maintaining its shape.
After looking into it a bit further, the scientist learned that what had kept the glass together was cellulose nitrate coating inside the glass, and thusly, safety glass was created.
In a physics professor Wilhelm Conrad Rontgen was working on a cathode ray tube when he shielded the tube with thick paper and discovered a fluorescent light generated by a material located near the tube.
He concluded that a new type of ray was being emitted from the tube. Further investigation soon found that the new ray could pass through most substances while casting shadows of solid objects and paving the way to X-rays as we know them.
Videos News India. Fireworks originated in China some 2, years ago, and legend has it that they were accidentally invented by a cook who mixed together charcoal, sulfur, and saltpeter -- all items commonly found in kitchens in those days.
The mixture burned and when compressed in a bamboo tube, it exploded. There's no record of whether it was the cook's last day on the job. One smell most people remember from childhood is the odor of Play-Doh , the brightly-colored, nontoxic modeling clay. Play-Doh was accidentally invented in by Joseph and Noah McVicker while trying to make a wallpaper cleaner. It was marketed a year later by toy manufacturer Rainbow Crafts. More than million pounds of Play-Doh have sold since then, but the recipe remains a secret.

The microwave is the result of an observation during a science experiment. Next he decided to heat an egg. Cutting a hole in the side of a kettle, he placed the egg inside and passed microwaves over the top.
At last there was an alternative to conventional gas and electric ovens. Food could be cooked much faster than people ever dreamed possible. Sixty years ago this year, Velcro was patented. Yet, the ever-popular hook and loop fastener — used the world over for anything from stopping jackets gaping open to preventing cushions from sliding off chairs — was actually the result of a mishap.
Observing the burrs under a microscope, De Mestral found thousands of tiny hooks that could easily attach to the small loops found in everyday clothing. De Mestral trialled several materials to make hooks and loops of his own so he could see which formed the strongest bond.
He found that nylon was perfect. In , chemist Spencer Silver, who worked at the Minnesota Mining and Manufacturing Company at St Paul, Minnesota, was supposed to be inventing a strong adhesive for the aerospace industry, but he ended up inventing a weak one.
Strangely, the tiny acrylic spheres of which this adhesive was composed were almost indestructible, and would stick well after several uses. At first, Silver wanted to sell the adhesive as a sticky surface that people could mount on noticeboards.
He envisioned them sticking notes to the board and peeling them off later, without ripping their nails to pieces on drawing pins. The idea did not catch on. In the Kellogg brothers were running a spa for people looking to eat healthier food. While making bread for their patients they left some boiled wheat out too long and it went stale.
When they rolled out the dough it turned into weird flakes. Not wanting to throw out all the dough, the brothers toasted them, hoping to get something edible out of it.
The crispy flakes were a hit! They experimented with other grains, finally settling on corn as the most popular. Yummy, crunchy potato chips were supposedly invented as a way to get back at someone!
