The Most Satisfying Machines In Human History

There haven’t been any machines for the majority of the history of our planet. Over the course of around 4 billion years. Innumerable plants and animals relied only on the resources of nature to ensure their survival and well-being. After that, humans appeared, and, historically speaking, we quickly started to invent things. That would change not just our lives but also the course of human history. The Most Satisfying Machines In Human History

Today, machines far outnumber people, and the difference is not even close. Worldometer estimates that there were 2 billion computers in use worldwide in 2015. Statista estimates that 15 billion cell phones will be in use by 2021. This does not account for every other machine, big or little, that we use on a daily basis. Our technological advancements have allowed us to go to the deepest parts of the ocean. The furthest reaches of our solar system, and even further. They are all over.

It’s amazing that we don’t think about them much considering how important they are to our lives. That might be as a result of the fact that many devices blend in with the background noise of the environment and are essentially forgettable. However, there are those that are so well made and excellent. What they do that seeing them gives a kind of happiness that cannot be experienced anywhere else.

Cookie cutter machines

Is there anything that compares to a delicious cookie? Although you can buy them in a box or bag and they could temporarily sate your sweet desire. Nothing beats freshly baked cookies that are still warm from the oven. You may even remember creating them as a young child by rolling out the dough and using your family’s assortment of cookie cutters to make them.

You probably haven’t given much thought. How metal cookie cutters are created despite using them dozens or hundreds of times throughout your life. Yet the process may be more rewarding than the cookies themselves.

A thin piece of aluminium is positioned in a circle around a metal mould, as described by Delish. At first glance, the aluminium ring appears far too huge to be able to take on the desired shape, making it almost impossible to believe. The aluminium ring and mould are then enclosed in a precisely tailored suit by a series of tiny metal appendages that successively press in from the outside. The diameter of the ring gets smaller with each press until it virtually disappears. The final press is the most satisfying because you can watch the last bit of slack go. Leaving you with a cookie cutter that is just the right form.

Automatic ice machines

Nothing is worse than needing a cool beverage and realise you neglected to fill your ice trays the previous night. Although you can fill them right away, it will still be many hours before they are ready, and in that time. You will be sipping lukewarm water.

We shouldn’t grumble because everything will work out in the end. Ice delivery from colder regions of the world used to cost more in the recent past (via Mental Floss). There are many models of automatic ice makers that are integrated directly into refrigerators. Which eliminates the need for manual labour. For a constant supply of ice, they rely on internal mechanisms and a connected water line.But since it all occurs in the background. It is incredibly practical but not very pleasant.

Get your hands on a countertop ice maker if you wish to observe a stylishly cool machine in action. They function by continuously running water over metal prongs using a small water pump. To attain freezing temperatures and gradually form an ice pellet on their surface, those prongs require refrigerant. The surface temperature of the prong then increases with the use of a heat exchanger. The ice particle drops off and lands in a collection dish (via Danby). The freshly formed ice is then transferred by a tiny plastic arm into a bucket. So you may add it to your beverage.

Cotton candy machines

County fairs, festivals, and sporting events all feature cotton candy. There is a good reason cotton candy stands are positioned such that you can observe the vendor in action. It’s mesmerizing to watch sugar floss emerge from nowhere and pile up on the paper cone. Additionally, it is a recent experience.

People used to consume spun sugar frequently before cotton candy machines existed. Although it operates on the same theory as cotton candy, it is much less pleasurable. Sugar was traditionally caramelised and spun with forks to create spun sugar. The result would essentially be a bundle of tiny sugar strands. This method, or a version of it, is still used by confectioners to create ornamental sugars for desserts.

John C. Wharton then created the cotton candy machine in 1899. In essence, it automates the entire spun sugar production process. Sugar is heated and then thrown through a series of tiny spinning holes (via How Stuff Works). You can use nearly any hard candy, but modern machines use floss sugar. Which is flavoured and made specifically for cotton candy. It will be simpler for your machine to melt the sugars and spin them into the candy floss of your fantasies. If you smash or grind it into smaller pieces (via Candy Turf).

Power washers

High pressure is useful for breaking objects in hydraulic presses, but it’s also helpful for thoroughly cleaning surfaces. If we’d had access to a power washer, duties during our childhood may have been a lot more enjoyable. However, it might not be a good idea to wash dishes under a pressure of a thousand pounds.

Although they are very different in design, power washers and hydraulic presses have a similar principle. They pull water from a water source, such as your garden tap. Force it through an electric or gas-powered water pump instead of using oil (via Explain That Stuff). The pressure is raised by that pump. Any extra pressure in a press is released by the release valve after it has been used to move a cylinder. The release valve is the key in the case of a power washer.

After being drawn in and compressed by the pump, the water is quickly expelled through a high-pressure line. A stream of water with significant kinetic energy is the end outcome. Thousands of pounds per square inch of pressure are applied to the stream as it emerges. That will suffice to clean virtually anything of dirt and filth. In the wrong hands, it’s also enough to hurt someone fairly badly. Proceed with caution, or sit back and relax while you watch YouTube compilations of pressure washing.

Pasta cutters

Automation has stepped in to meet the growing demand for precisely repeated operations as the globe has gotten more industrialised. For instance, the precise production of thousands of similar pieces is necessary for the construction of cars. Therefore, having equipment that can produce the same thing repeatedly is useful.

Although they are beneficial in many different industrial settings. Machines that precisely produce identical things have also made their way into kitchens. How else do you suppose you acquire macaroni noodles that are always exactly the same? Automatic pasta cutters operate on the same principles as other industrial machinery. Except they chop up carbohydrates rather than cutting metals or plastics.

Pasta is created in factories by combining wheat and water to form a dough. Depending on the final shape of the pasta, the dough is subsequently forced through various molds. The rewarding part comes at this point. The noodles are chopped into precisely similar parts as the dough is extruded into the molds by a spinning blade that swings through like a reaper’s scythe. Several hundred noodles fall into a collection tray with each revolution. Thousands of noodles can be produced every minute by commercial pasta machines (How It’s Made).

Hydraulic presses

Similar to an industrial shredder, a hydraulic press’s main source of satisfaction is seeing objects get destroyed. There is a whole category of online content, including entire YouTube channels. That is built on the inexplicable delight of witnessing objects get completely crushed by tens of thousands of pounds of pressure. Naturally, it isn’t how hydraulic presses were intended to be used. According to Grainger, hydraulic presses are frequently employed in production to punch out or compress materials. But if humans can figure out a way to exploit technology for amusement, we’ll do it.

Although there are many various kinds of hydraulic presses, they all essentially operate on the same principles. Moving the liquid inside the press, which is usually filled with oil, increases the pressure there. Pascal’s law states that pressure rises in all directions, which causes a cylinder to move toward a plate as the pressure rises (via ScienceABC). Crushed are any objects positioned between the cylinder and the plate. The strength of a hydraulic press’s materials and component parts has a significant role in determining the pressure it can exert. A pressure release valve is added to relieve any extra pressure and keep the press in good operating order, preventing the system from becoming overloaded. If you’re smashing gummy bears for amusement rather than breaking cars, too much pressure might not be a problem.

Automatic tree shakers

Even if it’s not the most effective way to gather fruit or nuts, spending the day at the orchard may be a great family adventure. You’re going to need a machine if you’re serious about acquiring your harvest as swiftly and easily as possible.

Driven through an orchard and parked close to the target tree are automatic tree shakers. A robotic arm is extended by the operator, which grasps the tree at the base and gently shakes it until all of the fruit or nuts fall to the ground (via Toronto Star). These devices can loosen hundreds or thousands of fruits or nuts in a matter of seconds as opposed to hand-picking each one from the tree.

Depending on the kind of food you’re gathering, what happens next. When it comes to nuts, they frequently fall to the ground before being swiftly gathered from the dirt by a second machine. However, you want fruit to land softly when you handle it to avoid bruising. Fruit farmers employ customized “tree shakers” that encircle the tree with a cloth flap. Fruiting bodies are caught on the canvas as they fall from the tree and then fall through a hole and into a conveyer belt.

Tattoo removing lasers

Lasers can be used to erase previous pictures from surfaces in addition to creating new ones. Laser tattoo removal has grown in popularity among those of us who no longer find the permanent artwork we’ve permanently etched on our bodies attractive.

In the past, dermabrasion, which employs a quickly spinning surface to essentially sand away layers of skin, was frequently used to remove tattoos (via Mayo Clinic). An alternate removal method that may be less stressful is provided by lasers.

We must first comprehend how tattoos function in order to comprehend how laser tattoo removal functions. Because tattoos are hidden in layers of the skin that don’t generally move or grow, they stay in place. Because ink particles are too huge for your cells to simply remove, they become permanently lodged in your body, which is not a fan of foreign items in general. The University of Utah claims that laser tattoo removal functions by dissolving the ink into smaller fragments so that your body can effectively eliminate them.

Because some colors respond more favorably to laser therapy than others, it may require numerous sessions to completely remove a tattoo. Even while the ink doesn’t actually disappear before your eyes when the laser passes over it, it is immensely satisfying to witness it happen.

Laser engravers

According to Britannica, engraving has been a common practice for more than 600 years, and for the most of that time, it has been a highly skilled technique created by human hands. Copper plates were first scored by engraving to produce repeatable prints. We still use it for that, but we also use it to add words or pictures to customize items like jewelry.

Due to technical developments that have sped up and improved the engraving process, it is more widespread than ever. In place of manual tools, computer-controlled lasers can quickly mark, etch, or engrave surfaces made of everything from metal to leather.

According to Earthweb, laser engraving works by noting changes in the surface’s conditions as opposed to removing material by using a CO2 laser to remove a little amount of material. Etching similarly doesn’t erase anything. Instead, it sufficiently warms the surface to cause melting while keeping it in place. For materials like glass or acrylic, it works well. The final aesthetic product is substantially the same, despite subtle differences in the specific procedure. Most significantly, you may still witness how a laser precisely and quickly changes a substance, almost as if by magic.

Industrial shredders

There is something tremendously pleasurable about seeing something torn to pieces, but we aren’t sure what it says about human nature. A paper shredder can help you experience this special thrill, but what if you need to destroy something more resistant than bleached wood pulp? Industrial shredders can help with it.

When several rollers twist into one another, catching supposedly invincible objects and shredding them to pieces, things get pretty entertaining. As items are disassembled, they fall onto a screen beneath the rollers, where they are sorted according to size. A component can be repeatedly run through the shredder if it is too large to be broken up all the way.

Although watching things get destroyed is entertaining in and of itself, knowing that these shredders are intended to lessen the quantity of garbage ending up in landfills can make you feel a little bit better about it.
