![]() When you move the mixture very slowly (and with little force), the particles inside have time to move and adjust to the new shape. ![]() What’s happening inside the mixture is pretty cool. That’s the coolest part about Non-Newtonian fluids – With the exact same substance, you can let it pour through your fingers but it can also be as hard as rock! In upper elementary, I use this as an experiment to wrap up a unit on matter. It’s not really solid (because it can be poured) but it’s not really a liquid because if you use enough force when you touch it, it’s hard and inflexible! What is a Non-Newtonian fluid? Meaning that it doesn’t quite behave like it should. Sometimes also called ‘corn starch mud’ (but honestly, that’s half as fun to say…), this simple Oobleck recipe is great as a combination of messy play and science!īasically, Oobleck is a Non-Newtonian fluid. ![]() This is an excellent activity for young scientists – Especially those who love messy experiments! Learn why we think science for kids is so important in this post. Printable: Oobleck recipe What is Oobleck? ![]()
