Liquid Sand Hot Tub- Fluidized air bed

  • Published on Nov 28, 2017
  • 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:

    Friend: what did you do on the weekend?
    Nephew: Oh nothing much, just went to my uncles
    Friend: what did you do at your uncles?
    Nephews: jumped into liquid sand.
