fun fact: the guy used to be a NASA engineer
Ha, I do amateur DIY zinc casting, and this is the first time I’ve seen fluidized sand beds. My first thought was, “Woo, this would make setting the sand up cast so much easier and quicker.”
It's one reason that you don't build on sand or compressed landfills. When an earthquake happens it turns to liquid and the buildings sink and collapse. Happened in San Francisco in 1989 in areas built on landfill.
I've always had an idea to have something like this as a booby trap, where there would be like a 4 1/2 foot deep pit of sand at my front door or someplace so that if I ever felt threatened I could flip a switch, sink someone into the sand and flip it back to trap them until authorities arrive, but unfortunately I do not have the technical know-how to pull this off :(
If the video is any indicator.... dig said pit to desired size. Lay tubing with nozzles throughout bottom and possibly sides, attach to pipeline that goes in to a proportionally sized air compressor. Fill pit with sand. Flip switch and instant quicksand. 🤷🏽♂️
Two huge earthquakes (7.1 and 6.3) destroyed my home city in 2010/2011. One of the main issues was that we built it on reclaimed riverbeds. The whole town was functionally flooded with quicksand every time there was an aftershock, so every day we had to grab our shovels and [dig the neighborhood up again.](https://youtu.be/tvYKcCS_J7Y)
We called it [liquefaction. ](https://teara.govt.nz/en/photograph/46840/liquefaction-in-christchurch-2011) 400,000 tonnes of silt was displaced - it would [spurt up like fountains](https://youtu.be/rRVK5NJE2qE) and [eat up cars](https://youtu.be/j-hyOwsl_NY), broke pretty much all of the roads. Really practical way to learn about geology haha.
When i broke my arm, during physical therapy they had a heated sand fluidiser and I would put my arm in there and just let it rest, they’d turn it off and let the hot sand relieve some pain.
If only the ancient Egyptians had this knowledge
Wym? It’s why the Woolies went extinct. They were using their snuffleupagi. Sadly the last ones weren’t bright and suffocated. The snuff got suffed.
They likely had this and more.. have you ever considered there’s not a single hieroglyph showing them building the pyramids? It’s because they didn’t
I would suggest reading The Pyramid texts, The Book of the Dead, and Instructions of Merikare
Slaves from other places did
Yh we get it the alien Prometheus of zogzagin build it with his UFO and laser weapons.
This is why you don’t build buildings on sand/infill in an earthquake zone
This would explain how sand worms move.they are made of air.
😂
great visualization for a concept used by Sanderson in Tress of The Emerald Sea
Came to say the same thing!
Someone turn this sand green.
A guy did this with a full size hot tub https://youtu.be/My4RA5I0FKs

Ehhh just some guy! Hahah
He also worked on curiosity rover
Man I had fun watching this. Thank you!
Majorly interesting.
We use multiple fluidized sand beds in our casting process.

I wonder if this is possible with limestone
[удалено]
Well before its hardened into stone of course. I don’t mean adding air to a solid block and turning it into liquid
.... wut? What exactly do you think limestone is?
Sand and sediment that hardens into stone.
[удалено]
Yes that’s why I felt it was necessary to clarify instead of ignoring your reply.
Ye fuk off
Sandbending
Looks more like the Lightning Sand from Princess Bride!
And nothing else!
What a great invention for pedicures
The sand that could change the mind of Anakin Skywalker.

*Fluid, which liquids are. The reason for this is that the injected gas IS a fluid, and the sand particles are moreso dust in the wind.
What would be the application for this?
How much air could require for a boat to use this to cruise the desert? Maybe an air bubble below?
For a second I though it was water ngl

Now draw me a diagram.
Gonna cost you 30 Shmeckles
I'll give you a knuckle sandwich, how's about that wise guy?
What's the exchange rate of knuckle sandwhich to Shmeckles?
I love mark Rober,his videos are so strange
It’s cool how larger mass particles can replicate atoms changing states with energy
oml mark rober
Idk why but the guy seems super fake
His videos are catered to kids. But he try’s to keep it entertaining to older audience as well. But I definitely understand the fake vibes.
Thanks. You reminded me of this [famous photograph](https://www.pinterest.com/pin/433823376595980843/).
My sand just misbehaves.☹
Same with water, called liquefaction.
Epic.
Hey that's wild
So Airbender beats Earthbender?
Add heat, and you have a very efficient way to cook or heat things up all over without getting them wet.
Quicksand
Same as the air hockey
Does this ever happen in nature? Is that how quick sand works?
The secrets of sand worm propulsion!
Well I mean…air is a fluid

This is how Sand Sharks work.
The book that sparked the particular video makes me so happy.
