Sea Monkey Day - May 16

If you were a kid in the 70s or 80s of the last century, you probably know sea monkeys, tiny creatures that come in the mail in the form of grains in a bag, pour them into an aquarium and they come to life and become cute little crabs.

May 16th is a day dedicated to these special creatures and the weird story behind the way they came to our aquariums.

It all started when a young American entrepreneur named Harold von Braunhut discovered in 1956 that fishermen in his hometown of New York were using as bait for fish in cute little crabs. These tiny crabs had a wonderful ability - in extreme dry conditions they enter a state of dormancy where they can stay for many years, and as soon as they are put back in the water they come back to life and become agile swimmers. In addition, fertilized crab eggs can develop within 24 hours and tiny white crabs hatch from them as soon as water with salt is added.

Brownhut's business sense immediately went into action and he realized that these sweet creatures could be marketed as pets to lots of people and make a lot of money.

The creatures that Brownhut discovered are called artemia. It is a type of tiny cancer that is common in lakes and salt lakes. Its commercial collection is possible in a handful of places around the world such as Siberia, the Great Dead Sea in Utah in the US and China. They are also found in the diesel lagoons and the Atacama Desert in South America.

Brownhut realized that people would not be excited to just buy crabs called Artemia as a pet, so he thought and thought and decided to call them "sea monkeys" because their long tails reminded him of monkeys.

He hired an illustrator named Joe Orlando who created comic books in which he built a whole world of magical characters from fairy tales of their own living in the underwater world.

American children were enthralled by the new animals that were discovered to the world and of course asked their parents to buy them, and sea monkeys became the flagship hit in America. Von Brownhut patented his invention and later developed with his team a "commercial breed" of Artemia - carefully selected and engineered crabs to suit longer aquarium life.

These tiny crabs have also become TV stars - they have appeared on shows like Spin City, Roseanne, Night Court, South Park, The Simpsons, Garry Shandling's show and Desperate Housewives. On October 29, 1998, sea monkeys went into space with astronaut John Glenn aboard the space shuttle Discovery. They returned to Earth after spending nine days in space and the eggs that hatched eight weeks later were apparently not affected at all by their travels.

Chocolate Chip Day- May 15

Who doesn't like chocolate chips?
Chocolate chips are a great addition to cakes, cookies, ice cream, pancakes, malawach, crepes, chocolate, coffee and even as a snack alone.

To celebrate the chocolate Chip day, add chocolate chips to all kinds of things as we listed earlier, or prepare something special with chocolate chips.

You can also arrange chocolate chips in special shapes like smiling faces or write something. Chocolate chips can also be an excellent decoration for cakes.

Who Invented the Chocolate Chips?

Like many things in life, chocolate chips were invented by accident. It began with the first chocolate chip crate prepared in 1937 by Ruth Wakefield from the Toll House Inn in Massachusetts. She wanted to make chocolate cake, but she was out of cocoa powder. So she mixed pieces of dark chocolate in the cookies with cookies. The cookies were a great success. In 1939, Wakefield signed an agreement with Nestle whereby the company would add its recipe to cookies for its chocolate packaging, and it would receive an unlimited supply of chocolate. At first Nestle added a small cutting tool to her chocolate tables. In 1941, Nestle began to produce the chocolate shaped chips. A few other companies followed suit.

Nestlé also has a chocolate chip brand called "Toll House" after the inn where the cookies were invented.

Nylon Stockings Day - May 15th

Nylon Stockings Day is celebrated in May 15 every year, in honor of the nylon socks, which are available in a variety of fashionable colors, and also in the color of the skin when their goal is to be invisible.

The history of nylon stockings

Until 1890, socks made of woven fabric such as cotton, linen, wool or silk were worn to protect the feet from the cold.

In 1920, when the hem of the dresses began to be high, it became common for women to wear tights on their bare legs. The tights of these years were made of real or artificial silk.

In 1938, DuPont developed the nylon patent. In 1939 they began using it in the process of making tights. The nylon stockings arrived in stores in the US and were received with great enthusiasm. They were cheap, durable and comfortable and every day 4 million pairs were sold.

On February 11, 1942, with the entry of America into World War II, DuPont stopped manufacturing nylon socks and shifted its focus to the production of parachutes, mosquito nets, wire and rope for aircraft and more. The nylon stockings were collected from the shelves and returned for military use. They became a kind of symbol of civil sacrifice for the homeland and women were asked to donate the tights they already bought for "Uncle Sam". There was a mass shortage of tights and trade in them moved to the black market.

At the end of World War II DuPont resumed sock production but failed to meet the high demand, which led to riots in American stores. Over time, DuPont was able to increase its productivity.

# Tips

The most annoying thing about long nylon stockings (tights) is that they have a tendency to tear easily. Every small hole in a nylon sock can turn into a run in seconds. The way to deal with a hole in the sock and prevent it from developing is to apply clear nail polish on the hole. So every time you wear nylon stockings, take a clear nail polish with you in the bag in addition to an extra pair of tights.

What can you do with nylon socks that can no longer be used?

Torn nylon socks have many uses and it is a pity not to recycle them instead of throwing them in the trash. They can be used as packaging for delicate clothes in the laundry, which you don't want to get tangled up in other clothes. They can be used as dust filters, to wrap fruit on the tree to prevent birds from eating them or as a cover for insect repellents. They can be used as rags for cleaning dust and sinks, a strainer for paints, storing onions and garlic, tying climbing plants and more.

How to celebrate Nylon Stockings Day?

Today, nylon socks come in a variety of colors and styles. Show off your fashion sense with different styles of tights. Go to the nearest mall, or shop to buy a sock and use it this day. Share on social media using the hashtag #NylonStockingDay

Yo-Yo Day - June 6

 Yo-Yo Day is celebrated every year on June 6th.

The yo-yo is a toy made up of two discs of equal size, made of plastic, metal or wood, and connected to each other in the middle of a hinge around which a wire is wound. To play yo-yo grab the wire at the end, throw it away from the body and yo-yo jumps down and returns up to the hand.

What makes Yo-Yo go back up is the gyroscopic inertia, the force in motion that causes the object to return to the state it was in.

The reason for choosing June 6 as the yo-yo day is unknown, but it may be because it is the birthday of Donald F. Duncan Sr., the American businessman who introduced the yo-yo into business and successfully marketed it as a modern toy in the 1930s. Duncan is sometimes mistaken for the invention of the yo-yo.

Yo-yo has a very long history. As early as 500 BC there is evidence that it was played in ancient Greece.

After the dolls, the yo-yo is the second oldest toy in the world.

Yo-yo became a popular toy in the ancient world through trade. He came to Scotland, England, India and Egypt and became a favorite game there as well.

To the modern world yo-yo came from the Philippines. In Filipino the origin of the name is "Tagalog" which means "to walk around".

In 1866 James L. Haven and Charles Hettrich patented  Yo-Yo's in U.S. But yo-yo became a success story in 1928, when Pedro Flores, an American of Filipino descent, opened a yo-yo factory in Santa Barbara, California.

How to celebrate Yo-Yo Day?

It is best to celebrate this day in a yo-yo competition, where everyone brings their unique yo-yo and together throws them. The winner is the one who managed to make his yo-yo fall down and come back up the longest, without stopping and without getting involved.

You can also learn to do very complicated and impressive tricks with your own yo, as in the video here:

Ferris Wheel Day - February 14th

Ferris wheel day is a day to go to an amusement park, no matter where, get on a Ferris wheel and take a spin between heaven and earth to celebrate the birthday of George Washington Jr., the American engineer who invented the first Ferris wheel in 1893.

In the 17th century there were playgrounds where passengers sat inside wooden seats attached to a large ring-shaped fixture and a powerful man would turn them around. The first facilities existed in Bulgaria and Turkey.

The first modern Ferris wheel was designed for the United States' World's Colombian Exhibition in Chicago, Illinois, in 1893. It was to compete with the Eiffel Tower, built for the 1889 Paris Exhibition.

The designer of the wheel was George Washington Gail Paris Jr. from Gilesburg, Illinois, and the wheel was named in English - Ferris Wheel.

The first modern Ferris wheel was really huge. It weighed about 2000 tons and was powered by two steam engines that each had a power of 1,000 horsepower. The wheel had 36 passenger compartments, each the size of a bus!

Each cabin could carry 60 passengers (20 seated and 40 standing), meaning a total of 2,160 passengers could ride in a wheel.

The Ferris wheel was 26 stories high and was one of the tallest buildings in the world. It took 20 minutes and cost half a dollar.

Today there are giant wheels in almost every amusement park. 

The tallest Ferris wheel in the world, High Roller, is located in Las Vegas and is 167 meters high. In second place is the Singapore Flair wheel, which rises to a height of 165 meters and in third place is the star Nanchang (Chinese: 南昌之星) which is located in Nanchang, the capital of Jiangxi province in China and rises to a height of 160 meters.

Sticker Day- January 13

Sticker Day is a day to celebrate in honor of all types of stickers wherever they are. Stickers for decoration, stickers that are used as labels to mark prices, stickers to mark property, barcodes, stickers (stickers) and more.

 

It seems obvious to us that there are stickers that can be used for a lot of things, but what was before the stickers were invented?

The idea of ​​labeling the product came from European merchants in the 1980s. In order to promote their goods they would stick paper labels on their wares with the help of chewing gum.

Even before the merchants, an older sticker emerged - the stamp for sending letters. The first official postage stamp in the world was the "Black Penny", a stamp issued by the United Kingdom on 1 May 1840. The purpose of the stamps was to indicate that the delivery for the letters was paid for by the sender, because until then the letter delivery method was cumbersome and inefficient. The payment for the shipment applies to the recipient of the letter who did not always agree to pay and tracking the payment was very difficult.

The sticker day falls on January 13 each year in memory of R. Stanton Avery, who was born that day in 1907. Avery was an American from Oklahoma City who invented the self-adhesive labels (modern stickers). He took out a $ 100 loan and built a machine that created the pressure-sensitive stickers, the world's first patent for adhesive paper. In 1953 he founded the company now known as Avery Dennison Corporation.

Since then the stickers have become more and more popular, and more and more uses have been found for them.

From childhood, stickers are used in kindergarten to teach children to catch up and develop fine motor skills. Kids love to collect colorful and decorated stickers and swap with each other. At school, stickers are affixed to notebooks and books and bags of sandwiches with the student's name. In supermarkets stick stickers with prices on products. There are stickers that stick to vehicles with political and other messages on them. Stickers have endless uses and when you think about it - this is a really ingenious and important invention.

Anniversary of dishwasher patent - December 28th

On December 28, 1886, the patent of the first prototype of the dishwasher was registered.

The dishwasher was invented by Josephine Cochrane, a wealthy American socialite, who was upset that her servants were constantly breaking the family's expensive china during the wash.

Before Cochrane's dishwasher, there were two dishwashers invented by men, but they were very unsuccessful and in practice failed to clean the dishes at all. That's why Cochrane said, "If no one else is going to invent a dishwasher, I'll do it myself!"

The dishwasher she invented was operated manually, and consisted of a copper meter inside which a wheel that turned with the help of an electric motor. An iron mesh was mounted on the wheel, with space for plates, cups and cutlery. As the wheel turned, hot water was sprayed on the dishes with soap from above, and then only hot water.

Cochrane unveiled her dishwasher at the World Fair in 1893 and sold it to friends, hotels and restaurants, but housewives showed no enthusiasm for her invention and she failed to take off. Cochrane eventually sold her company to Hobart, one of the inventors of the popular "Kitchen Aid" brand. It was not until the 1950s that dishwashers began to be sold in the United States and by the 1970s they had already become standard in American households.

Josephine Cochrane died of a stroke or exhaustion in Chicago, Illinois, on August 14, 1913, and was buried in Glenwood Cemetery in Shleville, Illinois when she was 72. In 2006 she was inducted into the National Inventors Hall of Fame.

Cotton Candy Day - December 7th

Today is a really sweet day. Sweet to the extent that it causes diabetes and destroys the teeth, but at the same time also brings up sweet memories of childhood.

The first cotton candy machine was created in the 19th century, ironically by a dentist. In 1897 dentist William Morrison and confectioner John C. Wharton invented the machine that heats the sugar and turns it into a liquid, then solidifies it again into thin strands reminiscent of glass. The lump of sugar threads that eventually form was very light because it contained mostly air.

The first appearance of cotton candy was in 1904, when it was introduced to a wide audience at the World's Fair in St. Louis, as a 'fairy Floss'.

In 1921, dentist Joseph Lascaux invented a new cotton candy machine and sold the candy at his clinic in Louisiana. He first gave it the name "Cotton Candy" and registered a patent for the machine.

In 1966, the world's largest cotton candy manufacturer, Tootsie Roll Industries, began producing cotton candy in bags called Fluffy Stuff.

Cotton candy is a treat that is usually served at street stalls at fairs, parties, carnivals, performances and public celebrations. The natural color of cotton candy is white, but it can be changed with food coloring. The cotton candy can also be made with other flavors.

More interesting facts about cotton candy

A strand of cotton candy is thinner than a strand of human hair.

Despite being thin, the thread can be very long. The longest cotton thread was created in July 2009 in Turkey and stretched over 1,400 meters  (4,593 ft 2 in). (Source: Guinness World Records)

Cotton candy has different names around the world. In England it is called Candy Floss. In Australia and Finland it is called Fairy floss. In the Netherlands, it is known as Suikerspin, which means "sugar spider". Traveling to France? Call it Barbe à papa, meaning father's beard.

Fountain Pen Day - The first Friday in November

 A fountain pen is a fancy and elegant pen, which always gives the feeling that the writer in it is a respectable person. The fountain pen is a pen with a nail and a container of ink. The ink comes from an ink tank and from there to the nail of the pen when the writing operation is performed on it.

There are very expensive fountain pens used by well-known people to sign important documents. There are also professionals who prefer to make a good impression when signing contracts and therefore use luxury fountain pens. There are also cheaper pens that are used for everyday needs.

Collecting fountain pens is a prestigious hobby, and there are fountain pens that come out in limited editions. The price of a pen due to a special edition may reach tens of thousands of Dollars.

The history of Fountain Pen Day

Going back to the beginning of the history of writing, these days humans would use chisels to mark on stone, ink on papyrus to mark shapes and pieces of charcoal to mark words on shells and leaves.

The ink was eventually invented, using various types of plant material, animals, and eventually iron and acetic acid. The ink was required for a new tool, and this tool was initially a goose feather with a carefully cut nail that was dipped in ink to pick it up and transfer it to paper.

It was such an amazing innovation that it stayed for a long time, but in the end a new piece was needed that did not require constant dipping, and constant cutting of the nail.

Then in 1636 a German inventor named Daniel Schwenter developed a new pen made of two pens. One pen served as an ink reservoir inside the other pen. The ink is sealed inside the pen with a stopper. The ink is pressed through a small hole to the writing point. It was a milestone that contributed to the invention of the fountain pen.

In 1809 Frederick Fölsch registered a patent in England for a pen with an ink reservoir. This happened in the wake of the Industrial Revolution in England which resulted in more people being able to read and write.

It is common to mark the year 1884 as the year in which the fountain pen was invented. Lewis Edson Waterman this year filed an effective patent for a non-liquid ink supply device. Waterman was an insurance agent who is said to have lost a large life insurance deal due to a leak of an ink pen on the policy. Waterman was motivated to develop a new non-liquid pen and founded the luxury pen company Waterman, which to this day is one of the leading pen companies in the world. Over the years it has become clear that the story of the insurance deal that was missed is an urban legend invented by the company’s public relations people, and apparently the invention of the resulting pen belonged to another person, it is not known who.

The fountain pen is the writing tool chosen for those who prefer a traditional, elegant and beautiful writing method. It has the advantage that it produces a cleaner and more consistent line than a few others.

The Fountain Pen Day honors this writing tool with this long and glorious history.

How to celebrate Fountain Pen Day?

One of the nicest ways to celebrate Fountain Pen Day is to buy yourself your own fountain pen. The price range of fountain pens can range from ten to tens of thousands Dollars. Once you start writing with a fountain pen instead of your simple pen, you will find how much more pleasant it is to look at your handwriting. You may want to start collecting well-designed and impressive fountain pens. This can be an exciting new addiction because through the pens you will learn a lot about the history of the world. What pens were used to sign the U.S. Declaration of Independence? And with what will the new President of the United States sign his documents?

Bathtub day is more than just an excuse to spend in a luxurious bath - this is the day to remember and appreciate the invention of the modern bathtub that has made our lives much more comfortable.

An old copper bathtub

Although archaeological finds have found that plumbing systems for bathing existed as early as around 3300 BC, the earliest bath found was in Crete, in 1700 BC.

Some sources claim that the first modern bath was invented in 1828, perhaps even October 7, Bath Day, but it turns out that they are based on Pike News, a fictitious story by H. L. Manken who wrote the false history of the bath (Bathtub hoax) and claimed that the use of baths in England began Only in 1828 and in the USA only in 1842.

Modern bathtubs in Western countries can be built-in, sunken or free-standing and many of them are made of acrylic or fiberglass materials, enameled or made of porcelain-coated steel. The traditional Japanese bath is usually made of wood. Today there are bathtubs in different designs and styles, and there is also a return to the retro style, of bathtubs as of old that stand on four legs.

October 7 is also The Barcode's Birthday

Barcode's Birthday- October 7th

On October 7, 1952, Joseph Woodland and Bernard Silver, recorded the first patent of the bar code.

Their idea was to create a code which digits are represented in lines that can be read using a suitable mesh, so that will be input to a computer (or computerized device, such as a cash register).

Their barcode does not look like a bar code known to us today, in the form of lines, letters and numbers, or square barcode suitable for smartphones (QR), but a symbol of a bull's eye made up of concentric circles.

Woodland and Silver were both graduate students in school then called Drexel Institute of Technology, Pennsylvania, Philadelphia.

The patent system was the immediate return of electronic information used by the product through patterns of lines of varying widths. Sixty years later, the bar code remains an enduring symbol of a time-tested technology.

Air Conditioning Appreciation Days- July 3- August 15

The invention of air conditioning is one of the best inventions in the world, which we all thank and cherish endlessly. The invention of the air conditioner did not just lead to improved comfort during the hot summer months - it turned places that could not be lived in places that could, kept the elderly and sick in their beds, improved air quality indoors for people with extreme allergies, allows better working conditions. It has led to the fact that around the world, new possibilities have opened up in production, and so much more.

The inventor of the air conditioner is Willis Haviland Carrier. Carrier was born in 1876 in Angola, New York, USA and died in 1950.

When he was 26, after graduating as a mechanical engineer, he was called by the owners of the  Sackett-Wilhelms Lithographing & Publishing Company of Brooklyn, New York, to find a solution to the heat and humidity that prevailed in the summer at the printing house and caused damage and loss; The rolls of paper were swollen and hard and the ink was not absorbed in them.

Carrier investigated the matter and decided to do the opposite of the heating operation in winter: if in winter to heat the air it is flowed through coils into which steam is compressed, then to cool the air one has to flow cold water through the coils. The invention was more successful than expected - the water in the coils condensed and accumulated as small droplets on the coils and the temperature dropped.

On July 17, 1902, the world's first air-conditioning system was activated in Buffalo, New York. This was the birth of air conditioning because of the addition of humidity control, which led to the recognition by the authorities in the field that air conditioning must perform four basic functions: temperature control, humidity control, air flow control and ventilation and air cleaning.

July 3 is also Independence Day in Belarus and A day without plastic bags
