The Happiest Devices in Human History

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 to 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 aluminum is positioned in a circle around a metal mold, as described by Delish . At first glance, the aluminum ring appears far too huge to be able to take on the desired shape, making it almost impossible to believe. The aluminum ring and mold 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.

Laser engraving

According to Britannica , engraving has been a human-made art form for the majority of that period that people have been doing it for more than 600 years. 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 functions by using a CO2 laser to mark changes in the surface’s properties as opposed to removing material in whole. 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.

Tree shaker

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.

Pasta maker

Automation has stepped in to meet the growing demand for precisely repeated operations as the globe has gotten more industrialized. 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 per minute can be produced by industrial pasta machines (via How It’s Made ).

Cotton candy

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 frequently consumed spun sugar before cotton candy machines existed. Although it operates on the same theory as cotton candy, it is much less pleasurable. Sugar was traditionally caramelized 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 flavored 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 ).
