Black dress
\nUp until the 1920s, black clothes were normally worn as a symbol of mourning and for at least 2 years. Then, in 1926, Coco Chanel sewed her famous little black dress, called \u2019\u2019Chanel\u2019s Ford\u2019\u2019 by Vogue, in memory of her beloved. At first, it was noted by movie divas, and then the dress became popular worldwide.<\/p>\n
Coca-Cola
\nPharmacist John Pemberton, a veteran of the American Civil War, made a concoction out of kola nuts and coca leaves. He recommended it to soldiers taking morphine for wounds to treat their nervous system. Later, he got a business going with a soft drink but then sold all his shares. The new owners started producing Coca-Cola with coca leaves cleared of cocaine.<\/p>\n
Karaoke
\nDaisuke Inoue, a Japanese rock musician, played for visitors of a cafe who wanted to sing in between the band songs. One evening he wasn\u2019t able to be there, so he gave his colleagues a tape recording with his part. Then, in 1971, he invented a machine that played music without the vocals, so the musicians relaxed while the public enjoyed singing to the beat.<\/p>\n
Play-Doh
\nThis substance had initially been used to clean wallpaper in houses equipped with fireplaces that accumulated soot. With the emergence of vinyl wallpapers, easily cleaned with a sponge, the cleanser lost its primary purpose. Then a relative of its inventor, a nursery school teacher, gave this putty-like substance to children to play with…and they were overjoyed! Later, the detergent was removed from the substance, replaced with a colorant, and the thing received its modern name: Play-Doh.<\/p>\n
Treadmill
\nThe prototype of a modern treadmill was created by Sir William Cubitt in 1818 to do something with idle prisoners, using their muscle power to mill grain. The prisoners held on to a horizontal handrail and walked a sort of endless staircase.<\/p>\n
Post-it notes
\nDr. Spencer Silver was in the process of inventing a lasting adhesive, but the resulting glue wasn\u2019t strong enough, and objects unstuck with ease. Then his colleague, Arthur Fry, proposed using this adhesive to anchor his bookmarks in his hymnbook. Soon, sticky papers for notes appeared in shops and are still used worldwide.<\/p>\n
High heels
\nIn Ancient Egypt, high heels were a sign of the status of high officials who wore high-heeled footwear to religious rituals. This included both men and women. Such shoes were also favored by butchers to avoid walking in blood, while Persian equestrians used high heels to hold on when shooting their bows. In medieval Europe, high heels were a privilege of the aristocracy, becoming more popular later. Finally, in the 20th century, the famous stiletto heels were invented.<\/p>\n
Bubble wrap
\nThe famous bubble wrap was invented by engineers Alfred Fielding and Marc Chavannes in 1957. It was initially to become a three-dimensional plastic wallpaper, but the idea didn\u2019t quite work out. Still, the inventors noted that the material could be used for packaging, and soon the patented bubble wrap became indispensable in various areas.<\/p>\n
Pillows
\nIn Mesopotamia, pillows were an attribute of wealthy people, while hard headrests were used to keep bugs and insects out of people\u2019s hair and face. In Ancient China, it was believed that soft pillows were useless, while hard headrests made of bamboo, jade, porcelain, wood, or bronze gave strength and protection from demons.<\/p>\n
Vaseline
\nIn the mid-19th century, oil field workers constantly fought the waxy substance that accumulated in the oil rig pumps. The British chemist Robert Chesebrough, though, saw an opportunity: he took a part of this \u2019\u2019petroleum jelly,\u2019\u2019 did some research, and found that it actually had useful properties. As a result, the range of its use in those early years became very broad \u2014 from curing wounds to cleaning carpets.<\/p>\n
Slinky
\nSlinky was actually not a kids\u2019 toy initially. Richard T. James, a naval engineer, was once working on a means for suspending sensitive shipboard instruments and accidentally dropped a tension spring that crawled away merrily. That\u2019s when the idea for a children\u2019s toy was born, and soon Slinky appeared in shop windows. James Spring Wire Company has sold more than 300 million of these toys.<\/p>\n
Tea bags
\nIn 1904, Thomas Sullivan, a tea and coffee importer from New York, decided to sell tea with more style by pouring it into silk bags. His customers found the novelty appealing, but for quite another reason: it turned out to be more convenient to brew the tea right in the porous bags. As a result, sales skyrocketed, and the idea became universally popular.<\/p>\n","protected":false},"excerpt":{"rendered":"
