Oobleck is a non-Newtonian fluid. That is, it acts like a liquid when being poured, but like a solid when a force is acting on it. You can grab it and then it will ooze out of your hands. Make enough Oobleck and you can even walk on it! Oobleck gets its name from the Dr. Seuss book Bartholomew and the Oobleck where a gooey green substance, Oobleck, fell from the sky and wreaked havoc in the kingdom. Oobleck, like the slime you like to make, is made up of polymer chains.
Polymers can be found just about everywhere – in places you might not even have realized. They are in natural materials like wool and silk (among many others), and also in many man-made synthetic materials like nylon and rubber. A rubber duckie, for example, is made of synthetic polymers. Even the double-helix strand of DNA is a form of a polymer known as a biopolymer. But what exactly is a polymer? The word polymer means “many parts.” The individual parts that actually combine to form a polymer chain are called monomers.
World Book Online Definition: Polymer, is a large molecule formed by the chemical linking of many smaller molecules into a long chain. The small molecular building units are called monomers. Monomers are joined into chains by a process of repeated linking known as polymerization. A polymer may consist of thousands of monomers. Some polymers occur naturally. Others are synthetic. One way to think of them is as a length of metal chain with each link being a monomer and when linked together they make a polymer or if you build a tower with Lego’s each Lego is a monomer and when you join then together it creates a polymer.
A chain molecule has a definite length, but, like a piece of string, it can assume a variety of shapes. This combination of molecular length and flexibility gives polymers many useful and unique properties. For example, rubber and numerous other polymers can be stretched to several times their normal length without breaking. The chains simply straighten into more extended shapes. Because of the large size of the molecules, polymers do not dissolve easily. They also have high viscosity (resistance to flowing).
We are going to make regular oobleck and fizzy oobleck to compare the two.
