Although still very young and not even 20 years old, but the child inventors can still change the world with their creations.
The United States and some countries around the world have no age limit for filing patents because lawmakers believe that the best ideas can come from a child's mind.
Whether the idea comes by chance or through research, young people have their own unique way to solve problems and change them. Here are the creations of young people under the age of 20, which has made the world we live in a completely different place.
Just a few months after his 20th birthday, Harvard University student Mark Zuckerberg officially launched his Facebook platform on February 4, 2004 with fellow students Dustin Moskovitz, Chris Hughes and Eduardo Saverin. .

In December 2004, the site reached 1 million users, but only 13 years later, the number was 2 billion globally and it continued to grow at a dizzying pace. Today, Facebook is a social network dubbed the advertising empire with revenues of more than $ 40 billion in 2017.
Thanks to Facebook, its owner Mark Zuckerberg also made his name on the list of the richest people on the planet with a net worth of $ 73.5 billion (data from Forbes).
The famous French mathematician, physicist and philosopher Blaise Pascal is famous throughout the world as the first to build mechanical computers. Since he was a 19-year-old boy in 1642, he was pressured by the taxman's hard work.

Faced with lots of numbers everyday, Pascal created a device called the Pascaline, which adds and subtracts whole numbers using the wheel system. Gradually, this device was upgraded and we use very popular today as the computer name.
On a cold night in 1905, 11-year-old Frank Epperson accidentally forgot a soda with a stick on the snow. The next morning, he woke up to find it was frozen, an incident that led to a great discovery.

Frank called it 'frozen lollipops' and patented it in 1924. Today we call it popsicles and kids love it.
In 1856, 18-year-old William Henry Perkin was assigned by the chemistry teacher to find out how to produce quinine less expensive. At that time, quinine was used to treat malaria. Perkin uses coal to make quinine but it does not cure the disease. However, Perkin creates a dark substance that over time will turn purple.
Natural purple for fabric dyeing was not previously available.(Image: Getty Images).
As it turned out, the compound he created kept a very good color on the fabric and was used as a purple dye. Before that, the garment industry had to work very hard and expensive to find purple dyes similar to lilac in nature. Perkin accidentally took the dyeing industry a step further with its products.
Chester Greenwood as a 15-year-old boy living in Farmington (Maine, USA), came up with the idea of covering his ears when skating. He asked his grandmother to sew the beaver pieces into a thick layer with a wire frame inside. The creation was later patented and he produced 50,000 pairs every year when he was 20 years old.

By the time Greenwood died, the world produced 400,000 pairs of earplugs every year and served the needs of so many people on the streets in the winter. In 1977, December 21 was first chosen as Chester Greenwood's Day in Farmington in his honor.
The French Louis Braille was blinded by an accident when he was 3 years old. But his physical imperfection did not prevent him from becoming a talented musician and created braille systems for less fortunate people like him.

Based on the code system used as the secret message used in the military, Braille created the braille system at the age of 15. He has published many books for the blind throughout his life.
A century after his death in 1852, he was exhumed to his grave in Pantheon, Paris, with his script in honor of him with many other French national heroes.
Born in 1906 in Beaver (Utah, USA), Philo Farnsworth soon realized that the mechanical system of a TV was very slow and it made scanning images quickly several times per second is unimaginable.
TV was never alive until Philo Farnsworth improved its scanning technology.(Photo: Everett Collection).
In 1921, at the age of 15, he sketched out his new system for TVs and submitted it to his homeroom teacher. In the description, he shows a vivid image of the television if he uses his system.
6 years later, he had his first patent. In September 1928, he perfected the image scanning system and presented them to the press to upgrade image transmission technology to a new level.
George Nissen was a gymnast and the inventor of the trampoline in the 1930s. Ever since he was a high school student, he and his coach had come up with ideas together. an object that enables people to juggle and tumble easily.

They eventually created a trampoline and opened a company to register a patent for this product. After being granted intellectual property, he continued to improve and launch the finished product in 1945.
Trampoline impressed by its advertising image. In it, Nissen took a photo with a kangaroo in Yonkers, New York, showing that this sports equipment is very solid and now it is an indispensable item of gymnastics.
Born in 1907, Joseph-Armand Bombardier of Quebec (Canada) soon created his own steam engine-powered mechanical toys from the age of 13. His father was not happy with his son's separation and reassembling the family car, so the father bought a new car for Bombardier to play with.

On the eve of New Year 1922 when he was 15 years old, he attached the engine to the sleigh with a huge fan behind him to create thrust. At this time, propeller cars were not even born yet, but he soon applied for patents for caterpillars in 1937 and gradually developed more of his products.
Despite his father trying to discourage him from seeing the dangers in this 'toy', Joseph-Armand Bombardier launched the Ski-Doo sleigh in 1958 and conquered everyone. .
Dubbed the 'father of water skiing' , 18-year-old Ralph Samuelson in 1922 accidentally invented this exciting water slide on Pepin Lake (Minnesota, USA). The invention was quite simple, he stood on a plaque tied to the back of his brother's canoe and kept riding on water.

But the board doesn't always skate on the water like that. After many calculations of parameters and material upgrades, he came up with a standard set for this sport and today we still play it as a watershed game.
35% of websites in the world run on WordPress platform and this is a product of 19-year-old Matt Mullenweg and 40-year-old Mike Little in 2003. As an open platform for content management and blog creation, WordPress is easy. It's easy to use and so anyone from a small business household to government websites will use it.

The company is currently valued at more than $ 1 billion and Matt Mullenweg is now the CEO of Automattic, the parent company specializing in developing products for WordPress.
Boyan Slat has had the bold idea of cleaning up trash in the Pacific since he was 16. Using 1 to 2 km wide pipes floating on the sea surface, underneath there are screens to help 'grab' the garbage.

The idea seems simple, but the optimistic The Ocean Cleaup project will clean up 50% of marine litter in 5 years, and they received $ 20 million in funding in 2017 to start work on the project in 2018.
Time is money, why waste time reading lengthy texts? In 2011 at the age of 15, Nick D'Aloisio created an automated and intelligent text summarizing algorithm called Trimit (later renamed Summly).

Using artificial intelligence, this technology can shorten text from 1,000 to 140 words with the most condensed information. The idea of quickly getting the attention of investors. Finally, D'Aloisio sold Summly to Yahoo for $ 30 million before his 18th birthday and continued to run the product himself called Yahoo News Digest for the next 3 years.
Invented by Canadian girl Andini (Ann) Makosinski, this unique flashlight does not use batteries but only runs on the palm of the hand. This invention won the highest prize at the Google Science Fair in 2013 and she has since received many other awards.

Flashlight operates on the mechanism of heat difference between outside heat and internal low temperature. This product is especially useful for field trips, outback expeditions or in less developed countries around the world. She has been invited to be a speaker at TED Talk 5 times and appeared on major TV shows around the world.
