The acetone actually dissolves the dry ice, making a liquid out of it. After you do that, dip something warm in it, like a flower, and you will see CO2 bubbles come off it as the dissolved dry ice boils.

I believe glycerol has similar surface tension to water; the difference in bubble size likely comes from its much greater *viscosity*.

Viscosity may indeed also play a role as you have indicated here

Isopropyl looks similar to acetone. I've done LN2 as well, but it's been too long to remember the details. I do remember seeing rapid formation of a cloud that subsided quickly

[@cahdoge]

The size of the bubbles is most likely be mainly determined by the viscosity, since water has the highest surface tension, but produces smaller bubbles. In higher viscocity, the escaping gas has more time to accumulate to larger bubbles.
As for the "vapour" its actually a mist of frozen/liquid droplets.
While it is correct, that a higher vapour pressure produces more vapour. The visual effect is down to the boiling point. If it's higher, the fog is more persistent, that's why the acetone only has a light mist. So to get a nice fog, you want your cold object boiling in a hot liquid in a cold room.
So hot glycerol and a regular ice cube might work even better at room temperature.

[@TommyTechnetium]

I have found that dry ice in hot glycerol works quite well. See pubs.acs.org/doi/full/10.1021/ed400754n

Event low Lying fog. And it's best to use pellets. More surface to react. Ps. It also cleanes floors as a side effect what's that about ?

[@10izfrk]

The liquid is not evaporating into the cloud. The dry ice is sublimating (CO2 going from solid straight to vapor)

[@TommyTechnetium]

It is indeed a bit counterintuitive, but the cloud is made of droplets of the same liquid the dry ice is placed into. This occurs because the liquid evaporates into the sublimed dry ice bubble, and then rapidly condenses. See pubs.acs.org/doi/full/10.1021/ed400754n

[@DeathMetalDerf]

Does it have to do with the relative density of the three different liquids? I'm guessing without looking at the rest of the comments first.

[@RGYT86]

Methylene chloride is interesting as well. It gobbles up the dry ice like it's nothing.

[@TommyTechnetium]

I've never tried this fluid. So it looks mostly like what you see with acetone? Why did you try this particular experiment?

[@randomrando8350]

The rate of sublimation in the acetone is pretty incredible.

[@TommyTechnetium]

I agree!

[@user-pr6ed3ri2k]

Rate of heat conduction and carbon dioxide absorbtion?

[@Nyx.Nax.9571]

Dry ice is dry nitrogen, a gas turned solid. So probably the fact it's different chemicals they each react differently than the last. It's a fun, but could be dangerous experiment so always have someone who knows what they're doing. Some may turn it back into a gas and some may not, some may take away the volume of the gas realeased and some may not.

[@calchen6603]

I would’ve thought that it has more to do with specific heat capacity: water holds an insane amount of energy per volume whereas acetone and glycerol pale in comparison. Surface tension might account for the slow bubbling but supplying the latent energy of sublimation should account for the denser clouds of CO2 gas. Thoughts?

[@TommyTechnetium]

This is definitely a possibility; perhaps thermal conductivity may play a larger role?

[@ArcYT]

instructions unclear: vape big clouds. got it

[@AnimeWolf5193]

I think the reaction to the glycerine is due to the liquid being thicker than water. It's too heavy for the vapor to get out.
I think the acetone can be explained by the leidenfrost effect. You can see air bubbles forming around the dry ice in the water, but not the acetone. I think this is is the result of different pressures between the two chemicals and how dry ice reacts. A google search showed me that acetone has a lower boiling point than water, which I believe is significant to my point but I can't explain adequately.
Put simply, dry ice in water creates the effect where it bubbles and creates vapor at a slow speed, due to the leidenfrost effect creating a barrier between the ice and water. But the acetone reacts faster because it can't create that barrier, releases gas more quickly, and therefore produces less vapor but still bubbles.

[@TommyTechnetium]

[@ericeasterday863]

Is it due to the rate of evaporation of the liquid medium?

In water, a thin gaseous film forms all around the dry ice. This insulates the dry ice from the water (similar to the Leidenfrost Effect). The same does not happen in acetone

[@handle_1969]

But why did it melt faster in the acetone?

[@TommyTechnetium]

Great question! large bubbles create an insulating layer around the dry ice, preventing physical contact between the dry ice and surrounding liquid. Because the liquid and dry ice do not touch each other, energy transfer from the liquid to the dry ice is slow. With acetone, no such insulating layer is formed. The liquid actually does contact the dry ice, so thermal transfer is rapid
