Watch: Ex-NASA Engineer Transforms Solid Sand Into ‘Liquefied Soup’
Imagine having an uncle
who’s a former NASA engineer and fills your family’s hot tub in the backyard with sand, only to liquefy it so that you can have some fun. That’s precisely what nephews of Mark Rober
experienced when he finally succeeded in his fluidized airbed experiment after 25 attempts.
Rober, who worked
in NASA’s Jet Propulsion Laboratory for nine years, wanted to create the fluidized bed for a long time. “You can find literally NO information online on how to make one like that. So I started combing through a bunch of patent drawings for massive industrial-sized fluid beds, and I noticed that instead of one big inlet, they all had a bunch of small holes to deliver air.”
Basically, to transform
the solid sand into a liquid, Rober used air. “If you take a tub of sand like this, and add in air in just the right way, it basically becomes a liquefied soup.”
