![]() Head to the right and destroy the silver panel to reveal a lever. Build them into a fan, then ride the current to the ledge. Use Lex Luthor's missiles to destroy them, revealing LEGO pieces. Hop up it and destroy the glowing generators on the right to lower the shields around the turrets. This will reveal some turrets that will shoot at you, but also provide a wall for you to hop up. Build them into a button, then press it to open the door in the back. Destroy the glowing computer in the center of the room to reveal LEGO pieces. Anyway you have Mercy Graves and Lex Luthor added to your party. You can name your character anything you want, but for the sake of this game I will be using the name "Rookie" to refer to your character. You can change anything you want about your character at any point in the story, so don't worry about getting everything perfect right off the bat. Keep in mind that what you select now is NOT permanent. There are TONS of things for you to customize, so have some fun with it. Before you actually start playing the game you will create your custom character. See, that was easy.Added Characters: Mercy Graves, Lex Luthor Solomon Grundy, Cheetah The Joker, Harley Quinnġ. That’s why plastics are used in so many helpful everyday products, from spatulas to car bumpers and from medical implants to fabrics for clothing.Īnd this is only the beginning, as chemists are constantly developing innovative new plastics-to help make aircraft lighter, hearts pump longer, food stay fresher, homes more energy efficient and so on. The molecules can be fashioned with various properties depending on what we need: sticky or slippery or lightweight or soft or hard or foamy or stretchy or … well, you get the point. Read More: Polyethylene density Plastics Chemistry: Always EvolvingĬhemists (along with other smart people) over time have come up with many ways to combine ingredients to make new polymers … and even to combine polymers. Thermoplastics are tough, too, but they often are used in less intense settings, such as lightweight bottles for soft drinks that are not subject to massive heat and friction like tires. For example, your car tires are made with thermoset plastics (often called synthetic rubber). An epoxy from the hardware store that hardens and cures when applied is an example of a thermoset.īecause thermosets are a three dimensional network of monomers, they can be very tough. This plastic behaves sort of like an egg: once it sets and “cures” (or in the egg’s case, once it’s cooked), it cannot return to its gooey, liquid state. If the monomers connect in a three-dimensional network, the polymer is called a thermoset. Polypropylene (the stuff butter tubs often are made of) is an example of a thermoplastic. This plastic behaves sort of like an ice cube: it melts when heated and solidifies when cooled … like water, over and over again. ![]() If the monomers join together lined up like a chain (picture a string of pearls), the polymer is called a thermoplastic. Read More: When was plastic invented? The Science of Plastics: Thermoplastics and Thermosets ![]() Without chemical bonds, life would simply be a chaotic maelstrom of elements. They also organize all those elements that combine to make up everything in the universe-including we humans. (As you see, chemical bonds are rather important-and not simply to enable modern plastics. And the resulting materials are called polymers. These monomers then are combined by chemical bonds into a chain or a network-this is called polymerization. When making plastics, these molecules generally are called monomers. Remember that magnificent, elegant periodic table of chemical elements that lists the building blocks of everything on earth? That’s the list of ingredients.Ĭhemists combine various atoms to make molecules, which are simply two or more atoms held together by chemical bonds. To make today’s plastics, chemists start with various elements (atoms such as carbon, hydrogen, oxygen and so on) derived from natural resources. Well, at least for me … Plastics Chemistry: How Plastic are Made While plastics can be high tech, advanced materials, understanding their basic construction is easy. No worries if you didn’t ace your chemistry class. Here’s a brief introduction to how chemists make modern plastics possible. Plastics are the result of the very real marriage of raw materials, engineering, and energy-all brought together through chemistry. Kidding … Actually, it’s science in action. Ever wonder how chemicals become plastics?
