Смесь крахмала и воды превращается в вещество, которое одновременно является жидкостью и твердым телом

Oobleck is both solid and liquid The Science Siblings took over the studio for some seriously squishy fun with their Oobleck experiment. Cornstarch and water turn into a wacky substance that’s a liquid one second and a solid the next. “So there’s a lot of different ways that people like to make Oobleck. Generally it’s agreed upon that it’s either a one-to-one ratio of water to cornstarch or a two-to-one ratio,” Adam Jacobson said. You can even hit it with a hammer. But Oobleck bounces back like magic. “Oobleck is a non-Newtonian fluid, meaning that it doesn’t follow Newton’s laws of viscosity,” Paige Jacobson explained. “Viscosity is basically how easy a substance is to flow or how thick it is. If you get maple syrup or molasses, it’s really slow. It takes forever to go outside the bottle,” Adam added. “That’s because it’s really viscous. But when you get stuff like water where it just flows real easily, it’s not very viscous. That’s the difference between the two.”
