Non-Newtonian fluids can’t decide if they want to be a solid or a liquid. They can be either a liquid OR a solid, depending on how much pressure you exert on them. So for example, if you poke a non-Newtonian fluid with your finger, you are putting force or pressure on it, which causes it to act like a solid. Without that pressure, it acts like a liquid.

Today we are going make Oobleck, which is a Non-Newtonian fluid like quicksand. It’s a solid! It’s a liquid! It’s both!
