TOP TEN SIMPLE MODERN INVENTIONS THAT CHANGED THE WORLD.
1. ZIPPER
A simple interlocking device that replaced Victorian hooks and eyes came our way in 1913.After many improvements, including an exec marketing the first galoshes with the device saying “Zip ‘er’ up!” the world has stayed together ever since.
2. BOTTLE CAP
The simple crimp top was patented by William Painter in 1892 and introduced a new era in keeping beverages fresh. Oddly enough he did not invent an opener.
3. BALLPOINT PEN
Cheap and reliable, the simple rotating ball-in-socket idea came out in 1938 and wrote its own history from there.
4. SAFETY PIN
The simple safety pin came into being quite simply while Walter Hunt, a New york mechanic, was idly twisting a piece of wire in 1849.
5. VELCRO
One side is hooks, the other side loops. How simple can you get? A Swiss engineer walking his dog in 1941 got the idea from the hooks on burrs.
6. CELLO TAPE
Cellophane tape went on sale in 1930 and went on to become one of the most famous and widely used products in history.
7. DuCT TAPE
Invented in 1942 to waterproof ammunition boxes, it went on to a post-war career sealing heating ducts, and then on to sealing just about everything.
8. FROZEN FOOD
Clarence Birdseye invented a simple method for quick-freezing food in 1923. “Birds Eye“frozen foods pretty much revolutionized an industry.
9. PAPER CLIP
The common paper clip is such a wonder of simplicity it seems puzzling that it wasn’t invented earlier. We had to wait ‘til 1890.
10. POST- IT NOTES
A scientist discovered an imperfect glue in 1940, but it wasn’t until it made the simple connection with paper and emerged as the Post-it note in 1980.
