Nice video. One question: Could you edit out or make the sound of the blowing air less loud in the future? It was uncomfortable to hear the noise for so long.

Fun fact, the exact same thing as you describe with sublimating water ice in your freezer also happens with CO2, which will result in it cooling down. That piece you were holding will cool down to almost 20 degrees lower than the -78.5 C number that is usually called directly from the phase diagram. I did my MSc thesis on this exact phenomenon and we published it last month. I would put the DOI link here, but KZbin blocks it... The title is "Experimental and theoretical investigation of the dry ice sublimation temperature for varying far-field pressure and CO2 concentration" and avaible open acces.

When I was young, my grandpa bought a large amount of dry ice. He took me out to the back of our house and filled a bottle of water halfway before adding some pellets of dry ice. He threw it, and in a matter of seconds, it exploded. We continued this thrilling activity for a while until we ran out of water bottles.

Reminds me about the time I definitely didn’t make a bunch of dry ice bombs as a teen. 😅

There was a company that made dry ice right in my little neighborhood and I used to buy chunks and throw them in the nearby river to make big clouds but I got in trouble doing that so I started putting it in containers to blow them up..... Learned the hard way not to put a chunk in a 2 liter bottle then inside of a cooler because the lid ended up in all the neighbors yards. The cops showed up very quickly but I told them I was trying to save it for later so I kind of got away w/ it... Shortly after that the company stopped selling it to minors. 😂😂

"Never put dry ice in a closed container..." - Frightened look at the fire extinguisher...

The 1st time I saw liquid CO2 was in a plastic bottle on Grant Thompson's channel. He expected the dry ice to burst the bottle but not before seeing a puddle of liquid in-between the pellets of frozen sublimating and melting CO2.

This explains why the money in my wallet disapears with no explanation.

Carbon dioxide doesn't come out of your car's exhaust. That's carbon MONoxide

Is it possible to wet* dry ice?

[@DANGJOS]

I've liquified dry ice a number of times before. One interesting thing I noticed is that, just like water ice, the unmelted dry ice can actually keep the rest of the liquid carbon dioxide at it's melting point temperature, which prevents the pressure from increasing further (although I'd still vent it a few times just in case).

That air blowing sound felt relly nice thru my headphone thanks.

[@paulcooper8818]

Cool demonstration.

[@brfisher1123]

Awesome!! I tried to tell you about this back in May of 2022 but never got a response, glad to finally see you try this out for yourself! :) 👍👍

[@DANGJOS]

@The Action Lab I always wanted to see you try putting dry ice in a super long tube (>160 feet) of water to see the dry ice melt and boil at the same time. It's probably way to difficult to do though

[@alaskacanoe6837]

here in Alaska .. it is known that snow and ice disappear during below freezing conditions below 30 degrees F .... this sublimation is estimated to be a huge part of where the actual frozen moisture ( ice and snow) just are gone into the atmosphere..

[@batlrar]

It makes perfect sense to me that it's water that creates the fog - that's exactly what happens with people's breath when it's cold out! In fact, if it's too cold, like if you're outside of a station on Antarctica, there's no steam coming from your breathe whatsoever, save for a tiny amount within the aura of your own body heat.

[@robrobitaille4235]

I love how much I learn from your channel. Keep up the good work!

Fun fact:

[@SimonWad]

I once did this by putting a pellet of dry ice in a cryovial (it's like an eppendorf but with a screw cap and a seal). I put the cryovial in a 30ml sterilin (a plastic tube), in a polystyrene box, in a warm lab oven. Didn't do anything so I went back to have a look - realised that the CO2 was liquid. But the box back in and walked away to wait, a bit scared. Went back a few hours later - the cryovial seal had released, explosively, driving shards of the 30ml sterilin into the sides of the polystyrene box.
