Liquid Sand

Former NASA engineer Mark Rober managed to turn normal sand into what he calls “liquid soup”, or in other words making sand behave like water. Technically speaking, this physical phenomenon occurs when a quantity of a solid particulate substance is placed under appropriate conditions to cause a solid/fluid mixture to behave as a fluid. “I’ve wanted to build one for a long time. But you can find literally NO information online on how to make one like that. So I started combing through a bunch of patent drawings for massive industrial-sized fluid beds, and I noticed that instead of one big inlet, they all had a bunch of small holes to deliver air,” said Mark.

“To make sand ripple and bubble like it’s a liquid, Mark used air. Basically, by blowing air into the bottom of a container of sand, he increased the space between individual sand particles, reducing internal friction and allowing the particles to move around more freely, the way they would in a liquid,” according to Bored Panda.
