Water filled hot tubs are soooo 2016.
Go to and use promo code “MarkRober” for $50 off any mattress. They’re super dope.
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.

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.

I dont think think science 🔬 is boring, i like science
Bird:wait…wut?
the greatest thing is that SOMEHOW he's not dirty out of sand
1:21 pausing a video be like……
You should bury the pipes 10 foot underground on a beach and just bury random people.
If I could explain this by my own words then imagine liquid molecules, we all know how they are separated from each other compared to a tightly packed solid. The air below the sand separates each grain of sand making each one of them kinda like a liquid molecule thus making that pile of sand act like water
1:34 see the rainbow?
Why would you show a pigeon dying? Wtf…
What if you stopped it when you were at the bottom of the hot tub
No science😡
Who made that beat! its sick!! @ 7:20
I ♥ science
I love science

Oddly satisfying 🧐
:21 so satasfying

4:20–4:40 Brilliant 😂
There is a point where magic and science are the same thing
0:56 if a bird sees this part, they'll probably not want to eat grain again…
Dont put the head under the sand. If the sand enters into your ears, you could have an ear infection or other problems

I don’t like sand. It’s coarse, rough and irritating. 
i like that velociraptor hunting patterns part
The sand looks like slime! You should get a lot of subs for this cool experiment.
Waaooo it's awesome
Dude this science part is gonna help me ACE my test in science thanks

I've been hauling frac sand for years. Unloading with air is an every day occurrence. The theory behind it being fluid never occurred to me. I figured just the brute force of air pushing it into a silo. Our bulk trailers have 3 air driven vibrators per pod, with a total of 3 pods. It takes 1 to 1.25 hours to unload 50,000 lbs without using the vibrators. I use mine every day and consistently average 35-50 minutes. Thank you for the explanation!
Sooo… the sandsea from FFXII is actually possible!?!?
I love science!
I feel like u will be the guy that starts installing theses in peoples backyard for cash lol
1:34 Oh look! A sandbow
That is soooo satisfying
This is what happened in Indonesia, liquefaction. The soil literally turned into a liquid.
Stop that thing when they are under lol
Bro if this guy isn't the coolest uncle than life is a simulation
This is awesome
Now I know how to make rainbow 😉

I think the science part is my favourite part of the video. Keep it coming
At 1:35 it makes a rainbow

Wow more views than xxxtentacion sad
this is how quick sand was made
Did you have sand in your peepee after that? XD
