5 topical inventions that girls and women invented

Wipers

In the winter of 1902, American Mary Anderson went to New York. During a trip on a city tram, a woman noticed that on a frosty day, the driver was driving with the windshield flaps open. The driver had to manually brush away the snow, blowing cold air into the cabin. Then the woman thought: why until now has no one invented a thing that could do it on their own? At the same moment, Mary opened her notebook and sketched the first version of the windshield wiper with a lever inside and a thin strip on a hinge for removing snow.

Back home, the woman refined her invention. When the hand-operated windshield wiper was exactly what Mary Anderson wanted, she took the sketches to production and ordered the model to be made. Already in 1903, a woman received a patent for the creation of wipers. The design consisted of a lever inside the car that controlled the rubber brush on the windshield and moved it from left to right, brushing off the snow. And during good weather, the wipers were removed so as not to interfere with the driver's view.

Similar devices have been created before, but Mary Anderson's product was the first working wiper. In 1905, a woman tried to sell the rights to a Canadian company, but they did not believe in the success of the invention. 15 years later, the patent expired, but mass production of cars increased. Cadillac was the first company to take advantage of Mary's design and install her wipers on brand new cars. The invention soon became standard equipment on every machine.

sippy plate

11-year-old Alexia Aybernathy looked after a little boy. Every morning she watched as the toddler carried a plate of breakfast to the table, spilling its contents along the way. Then the girl realized that something had to be done, otherwise the floor would be constantly in a mess. Alexia did not think long. According to her idea, it was necessary to create some kind of catcher of the spilled. For example, a larger plate so that the spilled porridge remains in it.

Just at this time, the girl participated in the school competition "Invent, Iowa!" and decided to present her brainchild on it. Alexia Abernathy picked up a couple of plastic bowls. Dad helped her cut a hole in a larger container that served as a rim. Then a smaller bowl was placed in the hole and it turned out to be a sippy plate. The girl wanted the containers to be connected using special protrusions, but this idea could not be realized. Then she decided to experiment with different types of glue and settled on hot, which gripped bowls perfectly.

Alexia submitted the invention to the competition and won. Then she won several more stages, but lost in the state competition. However, the girl was strongly advised to patent the invention and propose to some company. Then young Abernathy wrote 12 letters to different companies. One company responded, bought the license, and after a couple of years, Alexia Abernathy's non-spill plates were showing off in the country's largest stores.

Glowing paper

It's hard to believe, but a 10-year-old girl became the creator of the glow-in-the-dark paper. One day Becky Schroeder was sitting in the car and waiting for her mother to buy groceries at the store. The girl got bored and decided to finish her homework, but it was getting dark outside and it was getting harder and harder to see the pages of the notebook. At this point, Becky had the idea to create a paper that could glow in the dark.

Returning home, the girl began to remember all the glowing devices that she saw, and tried to understand how they work. The next day, Becky drove with her dad to a hardware store, where they bought a can of phosphorescent paint. The girl took paper, paint, went into the darkest room in the house and began to experiment. Becky turned on and off the light in the bathroom until she ran out with joyful shouts: "It works!"

The girl covered the acrylic writing board with phosphorescent paint. Next, it was necessary to hold the product in the light. If you put a piece of paper on a blackboard in the dark, it would also be illuminated and it would be easy to write on it. Becky Schroeder patented her discovery in 1974 and became the youngest inventor with a US patent. Over time, the girl's project turned into a successful business, and Becky took over as president of the company.

The Moscow Zoo is hosting Christmas trees!

The Moscow Zoo has been accepting unsold trees for several years now.

The campaign has been running since 2012.

This practice occurs in many zoos around the world.

Christmas trees are used as a useful treat for animals, toys or decorations for an aviary.

The zoo does not accept Christmas trees from individuals. Since the trees used to decorate houses can be dangerous for animals, fragments of decorations, tinsel, garlands can remain on them.

Almost all animals in the zoo like to play with trees, especially pandas, large cats. For some, the needles serve not only as a toy, but also as delicious food. It is rich in vitamin C, carotene and amino acids.

Goats, blue rams, elephants, capybaras and alpacas love to eat them.

In addition, some animals (snow leopard, lynx, puma, Amur tiger, forest cat) use tree trunks as scratching posts.

If you want to dispose of your home tree, you can do this using the "Christmas tree cycle" promotion. Recycled wood chips are often used in aviaries.

There are reception points in every district of Moscow.
