3. Potato Chips Potato chips are Americas favorite snack food. We spend almost 4 billion dollars on the every year. But they were actually invented on accident! Potato chips are Americas favorite snack food. We spend almost 4 billion dollars on the every year. But they were actually invented on accident! A chef named George Crum worked in a restaurant in Saratoga Springs, New York. One day in 1853 a customer kept sending his plate of fried potatoes back into their kitchen asking for them to be sliced thinner and fried longer. After a couple times George Crum lost his temper and he wanted to get even with the customer. He sliced the potatoes very thin, fried them till they were curly crisps and salted them. He was positive the customer would hate them so he delivered the potatoes to the diner’s table. To everyone’s surprise the diner enjoyed them and asked for more.

5. Post-it Notes Post-it notes are great for lots of things. You can stick them on the wall, whiteboard, desk, Calender to remind you of stuff. And it was invented on accident! Post-it notes are great for lots of things. You can stick them on the wall, whiteboard, desk, Calender to remind you of stuff. And it was invented on accident! Spencer Silver was working in a 3M research laboratory in 1970 trying to find a strong adhesive, but this was much weaker than what 3M already had. It stuck to object but lifted off very easily. It was super weak when 3M wanted an adhesive that was super strong.

It was super weak when 3M wanted an adhesive that was super strong. On a Sunday four years later another 3M scientist who’s name was Arthur Fry was singing in his church choir book used markers to keep his place in the hymnal, but the markers kept falling off. He remembered Silver’s invention and tried to see if they would hold the markers in place. Even though the adhesive was weak it held the markers in place and lifted off without damaging the pages.

They are now one of the most popular office products available. 3M began distributing post-it notes in 1980, ten years after Silver developed the super weak adhesive.

Within 8 years Marconi was sending radio signals 3,000 miles over the Atlantic Ocean. Within 8 years Marconi was sending radio signals 3,000 miles over the Atlantic Ocean. The first Radio stations started broadcasting in the 1920’s. The first Radio stations started broadcasting in the 1920’s. Early radio sets ran off big powerful batteries. That means that the radio receiver was big and heavy. Early radio sets ran off big powerful batteries. That means that the radio receiver was big and heavy.

7. Velcro George de Mestral invented Velcro from 1948-1956 on accident! George de Mestral invented Velcro from 1948-1956 on accident! One day he returned from a walk one day and noticed some cockleburs that were clinging to his jacket. A cocklebur is a maze of thin strands with burrs (hooks) on the ends that cling on fabrics or animal fur. George de Mestral knew this was a potential for a new fastener. After eight years of experimenting and developing the perfect invention. It consisted of two strips of nylon fabric. One strip had thousands of tiny hooks. The other had small loops. When they are pressed together they form a very strong bond. One day he returned from a walk one day and noticed some cockleburs that were clinging to his jacket.

9. Chocolate Chip Cookies The chocolate chip cookie was invented by Ruth Wakefield in 1930 on accident! The chocolate chip cookie was invented by Ruth Wakefield in 1930 on accident! Ruth Wakefield had run out of baker’s chocolate. So she broke some semi-sweetened chocolate into tiny bits. She had expected the chocolate chips to melt and the dough to absorb them. When she removed the pan from the oven, she was surprised. The chocolate hadn’t melted into the dough like she’d expected. Instead they melted and stayed atop the cookie producing chocolate chip cookies. Ruth Wakefield had just accidentally invented the chocolate chip cookie.

One day he was working in his lab at the University of Wurzburg, Germany. He was working with a Crookes tube (A vacuum which produced weak electron called cathode rays. When he was experimenting in a darkened room he noticed that a fluorescent screen three to four feet away was glowing. Roentburg was surprised when the black paper that surrounded the Crookes tube that prevented regular light from getting out. When he was experimenting in a darkened room he noticed that a fluorescent screen three to four feet away was glowing. Roentburg was surprised when the black paper that surrounded the Crookes tube that prevented regular light from getting out. A popular story says he discovered the rays’ power when he figured out that he had not knowingly photographed a key which was inside one of his books.

11. Light Bulb The light bulb was invented in 1879 by Thomas Edison When Thomas Edison invented his first light bulb after tons of tries the bulb burned up after 40 hours. Edison improved the 40 hours to up to 1500 hours of light! Edison experimented with over 1,000 different filaments.
