Explaining in caption 👇 When sand acts like a liquid under a constant flow of air from below, it’s doing something super cool called “fluidization.” Imagine you’re playing with a big pile of sand at the beach. When the wind blows gently over the sand, it’s like you’re sprinkling air underneath the sand, making it feel light and fluffy. Now, if you keep blowing air from below the sand with a constant flow, it’s like giving the sand a magic power. The tiny grains of sand start moving around and sliding past each other like they’re in a big dance, just like when you pour water and it flows smoothly. So, even though sand is solid, when it’s under a constant flow of air, it can act like a liquid, flowing and moving around. It’s all thanks to fluidization!. #
