I learned about four inventions this week and they were Coca Cola, induction motor, ballpoint pen, and the zipper. John Pemberton, born in Georgia, in 1831, was addicted to morphine after being slashed by a saber sword. He then experimented with coca wines. Coca cola is a sweet carbonated drink that contains caffeine from kola nuts. It originally contained cocaine. It led to the rise of soft drinks.

Second, I learned about the induction motor. Nikola Tesla, born in the Austrian Empire, in 1856, wanted to become an engineer and later worked with Edison’s company. Induction motors convert electric energy into mechanical energy. Rotating magnetic fields make it turn. Within 15 years electricity grew rapidly and it inspired the Tesla car company.

Third, I learned about the ballpoint pen. John J. Loud, born in Massachusetts, in 1844, was a trained lawyer but worked at a bank with his father, but was interested in genealogy and church activities. A ballpoint pen is a pen with a metal ball for the tip and uses two inks, oil based, and water based ink. The BIC cristal pen is the most popular pen in the world today because of the ballpoint pen.

Finally, I learned about the zipper. Whitcomb Judson, born in Chicago, in 1846, patented inventions in the 1880s, and was tired of buttoning his shoes. a device consisting of two flexible strips of metal or plastic that is closed or opened by pulling a slide along them, used to fasten jackets, bags, and other items. It led to the invention of the backpack in the 1950s.
