Liquid Sand Hot Tub- Fluidized air bed

Mark Rober - 2017-11-28

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

Here is the build info:  https://www.dropbox.com/s/rrt27f71gqjg41v/LiquidSandBedBOM.pdf?dl=0

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.

@Mark Brand it's not about the safety it's that feeling you get when you know something is going to not end well. And the fact of suffocating and you could never get out.

There are a lot of good teachers (not just in science!) who make learning enjoyable. My science teacher in the fifth grade was that way. Mark Rober makes learning fun, therefore, he is a good teacher. If they don't make learning fun, than IMO... not a good teacher.

Monidipa Saikia - 2020-03-07

since mark explained it in a VIDEO and you were able to visualize it thts why you were able to understand it easily
rather than only hearing it from your teachers mouth.
