Mark Robert, a former NASA employee, seems to have found another way to make science more entertaining: he turned sand into liquid and filled a Jacuzzi with it. Robert filmed everything on video and told how he managed to do it.

A former NASA engineer made a Jacuzzi where he turned sand into liquid Mark explains what a fluidized bed is — a physical phenomenon when particles of matter together with air bubbles acquire the properties of a liquid.
A former NASA engineer made a Jacuzzi where he turned sand into liquid That is, to make the sand become covered with ripples or bubbles, Mark used air. He put it at the bottom of the container, where the sand is located, and increased the distance between the grains of sand, reducing internal friction and allowing the particles to move freely — the way they would move in a liquid.
A former NASA engineer made a Jacuzzi where he turned sand into liquid "I've wanted to build such a thing for a long time. However, I couldn't get any information on how to do it. So I began to study a lot of patent drawings in this area and noticed that instead of one large air inlet, there are many small holes through which air flows."
A former NASA engineer made a Jacuzzi where he turned sand into liquid Robert had 25 unsuccessful attempts until he finally got a working project.
