Brilliant but simple inventions

Tipp ex

Tpp-Ex became a registered trademark with the German patent office in 1987. Earlier, in 1951, Bette Nesmith nvented the first correction fluid in her kitchen and began marketing the product in 1956 as she was making too many typing errors.

She was the mother of Mike Nesmith of Monkees fame.



post-it notes

Their invention is thanks to a Dr. Spencer Silver, a 3M scientist who in 1968 was busy researching adhesives in an attempt to find a super strong glue for use in aircraft construction. Instead, by mistake, he discovered the opposite and so the post it noted was invented
