Did you ever wonder how some of your favorite foods, products or toys came about? Believe it or not, they may have been an accident, or a failure of some other intention. Below, we found three mistakes we’re thankful for turned out to be what they are.
1. Most historians hold that the Chinese invented fireworks in the 9th century when they discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly in a bamboo tube and lit, it blew up.
2. In May of 1886, a law led John Pemberton, a pharmacist(药剂师), to rewrite the formula(配方) for “Pemberton’s French Wine Coca”, his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated(碳酸) water. His bookkeeper suggested the name Coca-Cola because he thought the two C’s would look good together, which is how what we call Coca-Cola, a world-wide drink came into being.
3. During World WarⅡ, scientists at the University of Birmingham invented the magnetron(磁控管)—an important heat-producing part of the microwave oven. While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels(仁), and found it to be a much more efficient way to cook. In 1947 Raytheon came out with the first restaurant microwave oven, which was six feet tall and weighed 750 lbs.

When kids at Archisha Singh’s school in Loudoun County have a birthday, no parents buy them birthday cakes.
Some schools are worried that children might become fat or eat unhealthy food, so they have banned(禁止) cupcakes altogether.
What do kids do? Birthday kids can donate a book. The headmaster of their school will then read it to their class. The headmaster also hands out birthday certificates(证书), special pencils, and makes sure the kids’ names are read out in the school’s morning news.
Parents can send stickers(贴纸), pencils and other things to students. None of the things can be food. If a child donates jump ropes or other sports equipment, that child may get his or her name on a certificate. It will then be displayed at school.
Archisha really misses cupcakes, especially those her mother used to make for her kindergarten class, but her school’s way is fun, too. “I like both ways,” she said.
The headmaster says it’s important that the school should be not only teaching, but offering healthy choices to kids. “There is a better life without cupcakes. If you eat a cupcake, then it’s gone in two seconds, but a book lasts a lifetime. The sports equipment lasts, and the kids can use it day after day.”
