Non-Newtonian fluids are liquids that are also sort of solid but also sort of neither but also sort of both? They’re very thick liquids or very giving solids, depending on what you want to call it. That’s why they’re so fun to do science experiments with. The Backyard Scientist went and filled up balloons with…
Ketchup, that delicious nectar of a condiment, is more annoying than it should be to pour out and enjoy. Why? Partly because of the dumb bottle it's in but mostly because it's a non-newtonian fluid in more than one way. Watch TED-Ed explain why it's so damn hard to pour out and what you should do instead in this…
There are some kinds of sludge, like quicksand, that you sink into. There are some kinds of sludge, like custard, you can walk on. And there are some kinds of sludge that just get stronger the more you stand on them.
It's not supposed to be that hard to figure out if something is liquid or if something is solid. If it flows like water, it's liquid. If it stays relatively still, it's solid. But what if it's a substance that breaks the laws of normal behavior and is both liquid and solid? Like non-Newtonian fluids?
The man of steel is impossible. Let's not pretend otherwise. The guy has X-Ray vision. He has super strength. He has supercold breath. He goddamn flies. There is no way he could do all that. But if there were, here's how they would work — according to what we currently know about the laws of physics.
The harder they're hit, the stronger they are. They stop bullets and let people walk on custard. They're non-newtonian fluids.
