Paint

Paints consist of a pigment suspended in a vehicle, which dries and hardens to form an adhesive film.

By Neep at the English language Wikipedia, 

Paint brushes were used as early as 2,500,000 years ago in the cave paintings of Altamira in Spain and Périgord in France.

The Ancient Egyptians mixed their colors with a gummy substance, and applied them separately from each other without any blending or mixture. They appear to have used six colors: white, black, blue, green, red and yellow, and green.

The Greeks and Romans added a greater range of colors to their paints and varnishes and began applying paints to house exteriors, decorations, wall paintings and ships. Most of their paints used egg yolk and  water as a base and the pigment was made from plants, sand, and different soils.


It is believed that oil paint was used in Europe in the later Middle Ages at first for decorating shields, because oil paint lasted better than the traditional water-based paint when it was in the weather, or if it was roughly treated. By the 16th century, oil paint had become the principal medium used for creating artworks.

Admiral Nelson ordered his ships to be painted yellow and black to distinguish them from the enemy.

The term "paint the town red" entered usage after a drunken Marquis of Waterford and a group of friends run riot in the English town of Melton Mowbray in 1837, painting the town's toll-bar and several buildings red.

John Goffe Rand was an American painter and inventor who patented the first collapsible paint tube on September 11, 1841. The tin tube allowed unused oil paint to be stored and used later without drying out. This invention revolutionized the way oil paints were used, making it much easier for painters to work outdoors and to experiment with new techniques.

Prior to Rand's invention, oil paints were typically stored in animal bladders or glass jars. These containers were not very portable or convenient, and the paint would often dry out or spoil. Rand's tin tube was a much more practical solution. It was lightweight, durable, and airtight, which prevented the paint from drying out. The tube also had a screw-top lid, which kept the paint fresh and prevented it from spilling.

Rand's invention was quickly adopted by painters around the world. It made it possible for painters to work outdoors for longer periods of time, and it also allowed them to experiment with new techniques, such as painting en plein air. The collapsible paint tube is still used by painters today, and it is considered to be one of the most important inventions in the history of art.

"Mummy brown" was a once-popular paint pigment made from ground-up Egyptian mummies. It was produced well into the 20th century, and only disappeared when the manufacturers ran out of mummies.

The first ever U.S. trademark was given in 1870 to the Averill Chemical Paint Company of New York City.

Japan's first patent was issued to Zuisho Hotta on August 14, 1885, for his formulation of an anticorrosive paint for ship hulls. The patent was entitled "Method for Preventing Corrosion of Ships." Hotta was a lacquerware craftsman who had developed a method of coating wood with a layer of lacquer that made it resistant to water and corrosion. He adapted this method to create a paint that could be used to protect ship hulls from rust.

In the United States, the first documented use of a painted center line was in 1911 along Trenton's River Road in Wayne County, Michigan.

The first white road lines in the UK were painted on the London-Folkestone road at Ashford, Kent, in 1914.



Metallic paints were invented for cars in the 1930s. They were made with fish scales and it would take 40,000 herring to make a single kilo of paint.

Spitfires were occasionally painted pink to blend in with the sunset and sunrise when used for low-level reconnaissance flights.

Before becoming Elvis's notorious manager, Colonel Tom Parker used to paint sparrows yellow and sell them as canaries.

The Hobbit crew used up all of the gold paint in Australasia for creating Smaug's lair. They used up so much paint that they had to actually pick more up from Germany.

Paint Drying is a 2016 British feature film about paint on a wall drying that plays for 10 hours and 7 minutes, It was created as a protest against censorship and the prohibitive cost to independent filmmakers which the BBFC classification requirement imposes.

The paint on the Eiffel Tower weighs as much as ten elephants.

The paint used on the Sydney Harbor Bridge drys so fast that, should a drop fall, it would dry before reaching the vehicles underneath.

Knife

The term "Swiss Army Knife" was coined and popularized by United States soldiers around World War II. The soldiers had trouble pronouncing the original name of "Schweizer Offiziersmesser" (Swiss Officer's Knife) and thus began calling the multi-tool a "Swiss Army Knife".

 Swiss Army Knives are red so they can more easily be found when dropped in snow.


Victorinox, the manufacturer of the Swiss Army Knife, lost 40% of its business as a result of the 9/11 attacks.

There’s an 1,800 year-old Roman version of present day Swiss Army Knife, complete with folding spoon, fork, spatula, pick, spike and knife.

Captain James Cook was fatally stabbed by a Hawaiian chief named Kalaniʻopuʻu on February 14, 1779, on the island of Kealakekua Bay. The dagger that was used to kill Cook was a British-made dagger that had been traded to the Hawaiians by Cook and his crew.

The phrase 'Passing the Buck' comes from using a buckhorn handled knife to designate the next dealer in a poker game; a player could decline the deal and 'pass the buck.'

Glenn Close framed the knife that her character used to try to kill Michael Douglas in Fatal Attraction, and it’s hanging in her kitchen.

It's legal to carry a switchblade in Missouri if you only have one arm.



Russian special forces use a knife that fires a bullet out of the bottom of the hilt—the user must hold the blade to shoot it.

As a part of the "Five Articles of Faith", the Sikh is required to carry a curved dagger at all times. This is specifically for the defense of the innocent and those in peril.

In 16th century Italy, music was engraved on knives so guests could sing together after they ate. Each side of the blade has musical notations and each knife represents one part for a singer. So, a complete set of knives actually come together to create a harmonious chorus.

The dagger found in Tutankhamun's tomb in 1925 was made from iron from a meteorite. It wasn’t until recently that scientists were able to confirm, using portable X-ray fluorescence spectrometry, that its composition, "strongly suggests an extraterrestrial origin."

Drill

Homo sapiens created the first drills around 35,000 BC. They would basically have consisted of a pointed rock being spun between the hands to bore a hole through another material.

It was discovered around 10,000 years ago that tying a cord around a stick, and then attaching the ends of the string to the ends of a stick, allowed a user to drill quicker and more efficiently. Mainly used to create fire, bow-drills were also used in ancient woodwork, stonework and dentistry.

The first hand drill, was a smooth stick, that was sometimes attached to flint point, and was rubbed between the palms. This was used by many ancient civilizations around the world including the Mayans.

Churn drills were invented as early as 221 BC during the Chinese Qin Dynasty. They were built of wood and labor-intensive, but were able to go through solid rock reaching a depth of 1500 metres.

Arthur James Arnot and William Blanch Brain of Melbourne, Australia patented the electric drill in 1889.

In 1917 the first trigger switch, pistol-grip portable drill was patented by Black & Decker marking the start of the modern drill era.

In its entire lifespan, the average home power drill in the UK is used only for 20 minutes.
