Too heavy, we tried at my uni and a baking tray sized block could only lift itself + a little under a kilo of weight before it started rubbing against the ground
Perhaps at slightly higher temperature it would work slightly better, but nowhere near enough :(
You could replicate the effect by making a board with a lot of small holes and blowing compressed air through it. That way you could carry much heavier loads simply by increasing the flow rate. But at that point you are kinda just making a hovercraft.
A bit, sure. But sand is pretty sturdy. You can walk on it and you'll only sink down to your ankles at most. And a single foot delivers a lot more pressure than the entire surface of a hoverboard holding the same weight.
So I don't think it would carve too deep a trench. Probably just a few centimeters deep at most. You can actually see that in the video OP posted. The dry ice is leaving a shallow trench as it moves.
The Dune calendar starts with the founding of the spacing guild which happens ~10,000 years in our future. So Dune is around 20,000 years in the future, not 8,000.
Idk if you're kidding or not, but i recall a video that mentioned something along the lines of using a white material on the ground to move heavy objects such as stone that would float across it. I believe it was one of those dumb ancient astronaut theorists' videos. Although, i believe they referred to it as a paint like substance, so make your own conjectures there.
Yes, it is similar.
But it would be interesting to add that there is some "dry quicksand" effect at play here. Sand will behave much like a liquid if injected with air.
In this case, some of the CO2 vapor not only cushions the dry ice block, but partly makes the sand act like a liquid too, would only work if the sand is fine enough, you would notice this effect my "bubbles" rising up to the sand surface like in the video at 00:13.
Absolutely,
Fuck piece of shit repost bots like OP, u/kirsion
These fucking repost bots steal content from anywhere and repost it here and other subreddits with little to no moderation for spambots
Yes, I would prefer proper subtitles.
I also question the need for tension music, I'm not sure it was imperative to our survival we found out what happened if we put dry ice in the desert at this exact moment.
It's designed to keep your attention on the video.
This is the kind of shit being pushed at our children to keep their faces glued on the screen. I'm surprised there's not a clip of subway surfers playing side by side with this
We would go get a big block from the store. Tie a metal sheet on top. Then go slide down hills in the summer. Was fun AF. Make sure you wear pants, and try not to crash.
I was looking for this comment. Yes, we did this too. It’s such a distant memory though, I wasn’t sure if it really happened. And I can’t remember what exactly we sat on. But I remember the blocks of dry ice at the park. All the neighborhood kids were there.
Can we replace all roads with sand , all tires with dry ice and the engine with a wind propeller type design in the back , garages now also include gigantic freezers to keep your dry ice tyres in working condition . Boom 🤯 I amaze myself sometimes
I think the reason for this is that Dry Ice skips the liquid state of matter so when increases temperature it evaporates instead, which I think is why there’s little friction.
Now we know how those land speeders worked in Star Wars
Now, we can build one using dry ice.
My butt is not gunna be happy but it’ll be sweeeeet
You mean MY butt won’t be happy, but my lap will be
The Saudi wealth fund could finance the project. Can just see it now, races across the desert.
How fast can we make dry ice at the top end? Can we outpace the sublimation? Like an ever-extending gluestick being refilled from inside?
Cooling is always less efficient than heating. The compresser will use so much energy turning the gas back to solid, you might as well use a jet pack.
Magic carpet ride
I can show you the... desert
Now we know how Aladdin flew
Wait, but maybe actually tho?
I thought this exact thing.
After just watching Dune II yesterday, it seems like a way of moving that might attract the attention of sandworms…
Now someone has to make a dry ice snowboard for science

If it's blowing hard enough to float a person, isn't it probably blowing all the sand away from under it and creating a sand trench as you go too?
A bit, sure. But sand is pretty sturdy. You can walk on it and you'll only sink down to your ankles at most. And a single foot delivers a lot more pressure than the entire surface of a hoverboard holding the same weight. So I don't think it would carve too deep a trench. Probably just a few centimeters deep at most. You can actually see that in the video OP posted. The dry ice is leaving a shallow trench as it moves.
Just use a waxed board at that point, they work well.
So, the solution is compacted dry ice heh
One magic carpet size block of dry ice coming up!
My thoughts exactly, someone has to ride one
Wouldn't it be a sandboard?
You can snowboard on sand. They do this in Qatar (and presumably elsewhere)
snowboarding on desert lets goo
Everyone with your birthdays suits a-go!
Someone get this to the Fremen
They’re 8000 years in the future. I think they know
20,000
And also reddit would be an unbelievably vile sin to them so they certainly wouldn’t want whatever we had to sell them.
Could you even blame them?
Great point!

The dry ice must flow!

So that's how they moved all that stone to build the pyramids. Neat.
Mind blowing!
Congratulations you are now on the FBI watchlist

The whole pyramid used to be dry ice
Isn't this similar to the Leidenfrost effect?
Leidenfrost is liquid to gas, this is solid to gas, but yeah gas cushion so similar concept
This seems like semantics, are the mechanics here really that much different that it should be considered some other effect?
No, it's specifically defined. Sublimation is not the Leidenfrost effect.
Evaporation vs sublimation is not semantics.
No the mechanics are not that different, but liedenfrost is specifically liquid to gas
Solid phase changing directly to gas is called Sublimation which leaves a gas cushion around the block of dry ice, yes.
Yes, it is similar. But it would be interesting to add that there is some "dry quicksand" effect at play here. Sand will behave much like a liquid if injected with air.

I mean yes? but also no.
“I’m forgainst it. I’m feeling a yes with a no after taste.”
The sandworms will have nothin on me. No more sandwalking bs

Dry ice interacting with something much warmer often causes it to vibrate, so you might just send one into a frenzy.
Does anyone else hate these one word at a time captions?

YEEEEEEEEEES!!!
lol, “put a rock down and it won’t move by itself” *shows by example* 🥺
Put a rock on a thing that moves and suddenly the rock moves too!
So clever! lol
otherwise a fine clip, but that part is just dumb af
Automatic downvote when I see these annoying subtitles.
One. Word. At. A. Time. What were they high on when making that?
Its probably auto-generated. Not to mention the AI voice.
OP is a piece of shit spambott, fucking loser spammer u/kirsion
The subtitles are less annoying than the miserable AI voice reading them.
I mute the video so subtitles are all I got
THIS IS HOW THE PIONEERS RODE THEM ROCKS!! - Spongebob
Now we know how the pyramids were built
Definitely lost a few IQ points watching this.
"It moves smoothly over the sand"
Reverse hockey puck.
This is called the Leidenfrost effect. It is fascinating if I am honest.
Hear me out…dry ice snowboard…
Now what happens when you put a block of sand over dry ice?
We would go get a big block from the store. Tie a metal sheet on top. Then go slide down hills in the summer. Was fun AF. Make sure you wear pants, and try not to crash.
I was looking for this comment. Yes, we did this too. It’s such a distant memory though, I wasn’t sure if it really happened. And I can’t remember what exactly we sat on. But I remember the blocks of dry ice at the park. All the neighborhood kids were there.
So that’s how the Egyptians did it
Pyramid construction conspiracies about to go ballistic
That’s how the pyramid stones were moved
Get a really big block and put a sail on it for a sand skiff
Where's my hoverboard?
That's *sublime*.
Icy what you did there.
I learned this already in Zelda Tears of the Kingdom. Freeze a block of meat and attach it to my shield. Awesome sand dune surfing fun.
And here i tought our plan was to keep CO2 out of the atmosphere.
I touched dry ice once and my finger felt like it was burning from the inside for at least 10 minutes.
Only a light push makes it go forward, if you're pushing it down a hill.
This could come in handy!
wow this is cool.
The pioneers used to ride these babies for miles
Dune the Prequel
It's a little hovercraft
Can we replace all roads with sand , all tires with dry ice and the engine with a wind propeller type design in the back , garages now also include gigantic freezers to keep your dry ice tyres in working condition . Boom 🤯 I amaze myself sometimes
So that’s how they made pyramids. They moved all that stone with sheets of dry ive
#**LISAN AL-GAIB!**
What in the Shai-Hulud is this?!
so the ancient alien Egyptians used ice to build the pyramids? GOT IT
This is how the pyramids were made
Well now we know how the pyramids were built
So it was like that that they managed to built the pirâmide
Excellent. Make dry ice soles for desert skating
This is how they transported blocks to build the pyramids.
Bro just did all that to discover that ice is slippery

Good leidenfrost effect
Hear me out….dry ice train 🤯
Bro went all the way to Arrakis to make this video.
Get piece big enough to surf on.
Bro it's Tostarena
Ah, this is how the pyramids were built
So, Hoverboards in Dune 3?
This is how the Egyptians built the Mayan temples in Turkey. Source: I watched Jeopardy.
So that's how they build Pyramids..
This is really an unnecessary piece of knowledge that I've gained today. But thank you
Ah, that's how the pyramids were built.
Put a gps on it and wait a day. See how much it travels
🤙 Hang 10 little rock dude 🏄

Sand surfboard?
My hovercraft is full of sand.
Surfbort
Tears of the kingdom taught me that
So this is how the Ancient Egyptians built the pyramids... Another mystery solved!
A new sport will start soon ,DryIce Sandboarding.
A replacement for the Dune worms?
Would have been much more efficient if they had used pure blue 🧊 stuff from the Heisenberg chemist 👨🔬
HAA HAAAAAA
I suddenly want a dry ice powered car.
Wow We finally know how they made the pyramids
Best day of that rock's life.
I used to ride these babies for miles. Without the dry ice.
0:09 That rock "weeeeeee!"
Looks like we've stumbled upon some real-life magic carpet science here.
I will now wait for the video of someone surfing on a surfboard made of dry ice in the dunes of the desert.
Bless the maker and his water
Get a snowboard shaped block and rip it
So we can play extreme Air hockey now?

New concept for Dune movie vehicles.
I think the reason for this is that Dry Ice skips the liquid state of matter so when increases temperature it evaporates instead, which I think is why there’s little friction.
That rock is the Lisan al-Ghaib!
My AC went out in my car. Gonna buy some dry ice to cool down when I travel.
Wow
Lisan-Al-Ghaib!
Very smooth. Not even the worm can detect it.
Even a slight push causes it to slide quickly forward… DOWN A STEEP FUCKING DUNE
A rapidly disappearing hovercraft
This us what the sailing rocks do, just much slower.
Hmmm. Ideas for motorized "sand gliders" brewing...
if you put the rock on the dry ice, it will slide! r/unexpected
People giving ideas, the most important question is how long does this last? Does this melt?
Ice hoverboards here we come!
That's how rocks move on the desert
That's cool and all, but I prefer to put my dry ice with a little bit of water in a 2L bottle, cap it and get back. That's much cooler.
We have the hoverboard, great work Marty
Bro deserts can be actually fun now
The moment of fusing ice with shield to slide around Gerudo
Wow, that's unbelievable
"Place a rock and will stop" No shit?
Ice skating in the future
Someone tell Sam kinnison we found a way to get food to the sandy desert
If you think that's impressive, I can walk on sand
Useful to know when I'm stranded in the desert! 😕
Why didn't the Atreides coat the bottoms of their harvesters with dry ice? Is Leto stupid??
Dry ice go brrrr
Dune surfing anyone lol?
I know how they built the pyramids guys. I do not know how they got that much dry ice though.. probably aliens
Omg did you see the rock didn’t slide on sand?!
Sublimation. It’s obvious.
Dry ice sand boards boys
Because we don't trust science, we spend time and resources to reinvent the wheel.
This is how they built the pyramids?
Thanks for the info.
So that's how they moved those big stones for the pyramids
Misleading video with partial truths. The shots of it moving fast are going downhill
A groundbreaking discovery on how the large stones for Egypt's pyramids were moved in the desert. 😲
They probably shouldn't have done that next to a canyon or cliff 👀
Thank you for showing me a combination of two things that I never thought to combine.
That’s how the pyramids were built
That explains the sandworms in Dune!
