I don't like sand. It's coarse, and rough, and irritating, and it gets everywhere.

Fluidized beds are used in industry for various reasons. They also happen to be really cool to play with and swim in. I made a liquid sand hot tub by adding air in just the right way.

Here is the build info: www.dropbox.com/s/rrt27f71gqjg41v/LiquidSandBedBOM…

Here is a video by the King of Random with more details on making one for yourself:
• Would You Swim In Liquid Sand?

I started a company called CrunchLabs where we build a toy together and then I teach you all the jucy physics for how it works. So if you want to learn to think like an engineer and have really fun time doing it, check out the current promotion where you get 2 FREE boxes at crunchlabs.com

You should also go subscribe to the CrunchLabs YouTube channel cause we’ve got some bangers in the pipeline- youtube.com/crunchlabs

Thanks to these folks for providing some of the music in the video:

I have been an engineer for 30 years and I used this minus to create a ball launcher which propelled them 30 km and it worked very well

I was just watching Dune with Timothee Chalamet and I remembered this video and realized that the worms in Dune make the sand move similar to how this phenomenon occurs all thanks to this video!!

There's an entire Brandon Sanderson novel built around this concept. It's so cool!
