![]() ![]() When the mixture of starch and water is right, try punching it and see whether it becomes solid. Add the starch slowly after a while, because you do not want to make it a solid, but rather a non-Newtonian liquid. Adding starch and mixing it with a spoon or by hand is the way to go. The best way to make Oobleck is to start with water in a bowl, usually a cup of water. Adding food coloring is optional, but it helps if the demonstration is made for children. Mixing it with water is enough to make it into a non-Newtonian fluid. Oobleck is made out of cornstarch, typically. Oobleck is typically used in science demonstrations involving speakers, because of the way it reacts differently to low and high frequencies.ĪlejandroLinaresGarcia, CC BY-SA 3.0, via Wikimedia Commons – cropped How to Make Oobleck – Starch! When moved around slowly, they will be liquidy but as soon as they are exposed to high stress, for example, a punch, they will harden immediately. Namely, they behave differently under slow flow and under high tension. Non-Newtonian fluids behave differently than other fluids and are named thusly because they do not follow Newton’s law of viscosity. As one can guess, Oobleck is a non-Newtonian fluid. A young man must rescue a kingdom from a sticky green substance called the Oobleck. It comes from a book called Bartholomew and the Oobleck, written by Dr. Oobleck is a name for a non-Newtonian fluid. Here is a detailed explanation of what Oobleck is and how to make it. ![]() Such is the Oobleck, something most people have heard of but often have no clue about what it does and how to make it, not to mention how it works. There are fun aspects to science, which when applied in practice, can be entertaining for both adults and children. Whether internet technology gives us free access to entertainment on a daily basis, communication or business opportunities, or a refrigerator that keeps our drinks cool and our food from going bad, technology keeps us safe and entertained. Science allows us to enjoy all sorts of things. ![]()
