Every year on January 17, an unusual holiday is celebrated in the world - the day of children's inventions. Interestingly, the birthday of the famous American politician Benjamin Franklin was chosen as the date of the holiday.
In 1718, 12-year-old Benjamin appeared on the beach with two unusual objects resembling fish fins. Despite the ridicule of friends, Franklin that day swam much faster than his peers. This is how swimming fins appeared.
And at the age of 15, Franklin gave the world another useful thing - a rocking chair. He attached curved runners to an ordinary chair. It was on Franklin's birthday that they decided to establish a day of children's inventions.
In 1824, the 15-year-old son of a French shoemaker, Louis Braille, developed a typeface for the blind, named after him - Braille. At the age of one, the baby accidentally stumbled upon his father's boot knife and by the age of 5 he completely lost his sight. But Louis learned to read with a typeface of his own invention. This method is still used all over the world, and after his death Braille himself was buried in the Parisian pantheon.
But American Frank Epperson did not even suspect that a glass of lemonade forgotten on the street in winter would help him become a millionaire. In the morning, lemonade turned to ice, and 11-year-old Epperson is called the discoverer of the "fruit ice" recipe. Moreover, Frank himself initially did not think to launch his invention into mass production. He remembered about it only 18 years later - in 1923, when he opened a small factory for the production of frozen lemonade. In 1928 he sold the patent and received substantial royalties on a regular basis.
Modern snowmobiles are replacing the traditional northern mode of transportation - dog sledding. And the first tracked snowmobile was assembled in 1922 by 15-year-old Canadian Joseph-Armand Bombardier from his father's old Ford.
American teenager Benny Benson submitted his drawing to the Alaska National Flag Competition in 1926. It was his sketch that was recognized as the best and approved as the official flag of the northernmost American state.
In 1930, 16-year-old John Nissen from Iowa assembled an unusual piece - he pulled an army tarpaulin over an iron frame using rubber shock absorbers. This became the prototype for the sports trampoline. Soon, trampolines began to be installed in scout camps, where they caused an unprecedented enthusiasm.
But the Englishman Sam Houghton received a patent for an invention at the age of 5. His idea for a broom with two heads for cleaning large and small debris went through a rigorous patent process, and now Sam is officially an inventor, and the copyright for the production of such a broom is protected by law.
