Ex NASA Engineer Makes Everyone Freak Out When He Turns Sand Into ‘Liquid Soup’, And Here’s How He Did It
Do you believe that science can be entertaining? Well, today I have come up with an interesting story about a former NASA engineer Mark Rober, who has really tried his best to make science as entertaining as it can be. Let’s get on board with us and see how and what he did on the same.
Sand Behave Like Water
He actually demonstrated a live process in which sand behaves like water. Not only he just documented his experiment but even filled his tub to add more fun to the process. In his experiment, he also explained everything in an easily understandable manner with a touch of humor so that the audience find it interesting.
His Hard Work
Before starting, he researched online for long but couldn’t find anything relevant. So he started combing through a bunch of patent drawings for massive industrial-sized fluid beds. And after 25 failed versions, he finally presented his first working design in the form of a video and created a ‘liquid sand’ hot tub for a long time.
In the experiment, Mark explored a phenomenal fact called “fluidized beds.” It is a physical phenomenon that occurs when a quantity of a solid particulate substance is placed under some conditions to cause a solid/fluid mixture to behave as a fluid.”
How The Process Worked
Mark used air to make sand ripple and look like a bubble as if it’s a liquid substance. Basically, he blew air into the bottom of the container of sand to increase the space between individual sand particles so that the internal friction is reduced. This, in turn, allowed the particles to move around more freely, the way they would behave being in the liquid state.
The Entertaining Video
Watch out the amazing video below and take a dive into the tub of liquid sand. In the video, you will also see how his nephews joined the fun!
So, guys, I hope all your doubts about making a hot sand tub are now unfolded with the video above. And, let us know if you would like to dive in such an amazing tub of “fluidized sand” yourself.
