![]() Oobleck is made from cornstarch and water, and the starch components are suspended in water which causes its unusual behaviour. Oobleck is easy to make and is commonly used to display the properties of non-Newtonian fluids. Now that we know how Newtonian fluids differ from non-Newtonian fluids, let's take a look at some common examples of non-Newtonian fluids. Force applied to the ketchup changes the viscosity/flow. When you shake a bottle of ketchup, the sauce becomes more liquid. In non-Newtonian fluids, the viscosity changes when under force/stress to either more liquid or more solid.Īn example would be ketchup. Non-Newtonian fluids are fluids that no dot follow Newton's law of viscosity. ![]() The viscosity of water is certainly not affected by applied stress. At 0˚C it turns into a solid, and at 100˚C it is a gas, but between those temperatures is behaves like a normal fluid, and has a constant viscosity. Stress does NOT affect this type of fluid.Īn example would be water. In summary, he observed that Newtonian liquids have a constant viscosity/flow, and that their flow behaviour only changes when there is a change in temperature or pressure. ![]() Sir Isaac Newton described Newtonian fluids in Newton's law of viscosity. To understand non-Newtonian liquids/fluids, let's take a look at Newtonian Fluids and compare the properties to non-Newtonian fluids. In this post, we are going to try our best to explain what a non-Newtonian liquid/fluid is, and give you a few examples on non-Newtonian liquids. You can also purchase and make non-Newtonian liquids like non-newtonian putty, that are designed as science demonstrations to showcase the properties of non-Newtonian liquids. Non-Newtonian liquids are everywhere they are in everyday items around your home and even in your body.

The definitions are sourced from the famous and open-source WordNet database, so a huge thanks to the many contributors for creating such an awesome free resource. ![]() In case you didn't notice, you can click on words in the search results and you'll be presented with the definition of that word (if available). For those interested, I also developed Describing Words which helps you find adjectives and interesting descriptors for things (e.g. So this project, Reverse Dictionary, is meant to go hand-in-hand with Related Words to act as a word-finding and brainstorming toolset. That project is closer to a thesaurus in the sense that it returns synonyms for a word (or short phrase) query, but it also returns many broadly related words that aren't included in thesauri. I made this tool after working on Related Words which is a very similar tool, except it uses a bunch of algorithms and multiple databases to find similar words to a search query. So in a sense, this tool is a "search engine for words", or a sentence to word converter. It acts a lot like a thesaurus except that it allows you to search with a definition, rather than a single word. The engine has indexed several million definitions so far, and at this stage it's starting to give consistently good results (though it may return weird results sometimes). For example, if you type something like "longing for a time in the past", then the engine will return "nostalgia". It simply looks through tonnes of dictionary definitions and grabs the ones that most closely match your search query. The way Reverse Dictionary works is pretty simple.
