I don't like sand. It's coarse, and rough, and irritating, and it gets everywhere.
Here is the build info:
Here is a video by the King of Random with more details on making one for yourself:

Summary: 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.

By popular demand I have shirts now! I picked the high quality shirts and make $0 on all items which is why they are priced handsomely.

I make videos like this once a month all year long while supplies last:
