Sand Acts Like A Liquid When Air Is Applied At The Right Places
Fluidization is the term used to describe this process in which sand acts like a liquid. When you place a continual flow of air below any fine powder or granulated substance, it will result in this phenomenon. By forcing its way to the surface of the substance, air reduces friction, making sand seem & behave like a liquid on the surface of the material.
I'm baffled as to how I missed this process in which sand acts like a liquid.
What could be more exciting than staring at sand and imagining it to be liquid?
You trust what your eyes are telling you, don't you?

Don't be too quick to rule out the possibility that the surface you're walking on will suddenly begin to move. It would be similar to walking on a waterbed in some ways.
And it is feasible to do this through the application of scientific procedures.
Consider the scenario in which the sand on the beach you're walking on suddenly turns to liquid.
Putting a massive air compressor beneath the seashore is really physically achievable if someone manages to do it successfully.
Does it sound more like science fiction than it does like actual science? That's exactly what I was thinking. However, in the past, this phenomenon has been put to good use in many ways. This is something I wish had been taught to me in science class.
Have you ever noticed how quickly an object sinks into the sand when it is placed on top of it?
Yes, during fluidization, the liquid sand allows things to sink or float on their surface, depending on their size and shape.
When you witness something like this, it's unnerving since it goes against everything you've previously believed to be possible.
But enough with the ramblings of the tongue.
See the procedure in action in this video provided below, in which a pail of sand is used to simulate the process in miniature. When the experimenters run their hands over the sand, the sand drips down their hands just like water, which is fascinating to witness.
However, I indicated previously that this would be put to good use. However, numerous companies have been utilizing it for many years before I became aware of its existence.
During the 1940s and 1970s, fluidization was widely utilized in the coal mining sector, and it saw a resurgence in the 1990s.
As you may guess, working with large quantities of granules in a more fluid state is much easier than working with smaller amounts. They're more convenient to travel between two locations. Fluidization also aids in maintaining the same temperature throughout all particles.
Consider the heat of the sun beating down on a particular stretch of beach. When the sand begins to flow, the particles combine, and heat is released, which spreads across the surrounding region.
Isn't science amazing, to say the least?
Where Can You Observe Liquid Sand In Action Today?
The concept of sand acting as a substitute for water is still used in several industrial operations, and it has uses in the oyster and powder coating industries, among others.
Some Commonly Asked Questions
Why Is sand able to behave like a liquid?
Because both sand and cereal are granular materials, they may both flow like liquids, yet they are not the same type of liquids. This means that they are composed of solid particles, yet they have the ability to flow like liquids.
Is sand considered a liquid or a fluid?
Despite the fact that individual grains of sand are solid when a large number of them are together, they behave astonishingly like a fluid - think of sand dunes crumbling, avalanches occurring, or sand pouring through an hourglass. Granular materials are what they are referred to as, and the mechanics of how they move is still rather obscure when compared to fluids.
Is sand capable of flowing with water?
Scientists have discovered that when poured, sand acts like water, resulting in the formation of water-like droplets.
Is sand able to flow?
The pouring sand appears to be a liquid when seen from a distance; it cascades down the middle of hourglass-like water from a faucet. However, up close, individual grains may be seen sliding against one another and producing a mound at the base that retains its shape, much like a solid.
STRANGE Sand Acts Like Liquid
Why Does Sand Pour Like A Liquid?
When you pour sand, the granules tend to bounce about a bit. They are not a cohesive group. As a result, each bounce permits them to move in relation to one another. They have the ability to move independently, much like droplets of liquid.
Several users on Reddit debated about a video in which a man is fluidizing white sand, making it appear like a liquid. That was really cool though.
"I bet with the right amount of finesse you could convince a couple thousand people that lava is actually cold and just the air thats moving through that makes it look like its boiling"
"For immobile patients in the hospital that are at high risk for bed sores, we often use beds filled with sand that have air pumped through as it prevents the bed sores without having to constantly reposition them he patient which can be painful and uncomfortable for them."
"Really?? That's a frigging cool application of this! Out of curiosity, are these beds sold at insane mark-ups on the basis that they're intended for a medical application?"
"I don’t know what they sell for. My hospital rents them by the day. Someone told me it’s about $3,000/day but I have no way to verify that."
"Good goddamn!! That's nuts!!!!"
Making a fluidized bed is as simple as pushing air through the bottom of a container filled with sand. This increases the amount of space between the sand particles, allowing them to move more freely among themselves. Because internal friction in the sand has been reduced, the grains are free to move around like particles in a liquid. So sand acts like a liquid due to this.
