HEY GUYS whats a chemical like this?

DON'T SQUIRT DCM AT PEOPLE: THAT IS A VERY RECKLESS IDEA AND COULD SERIOUSLY INJURE SOMEONE -Texium

LOL so I didnt see my secret squirter post available for viewing so i assume its taken down for what ever reason lol...

So are there solvents that could be squirted simply because they have a high vapor pressure. Like DCM from a squirting device would suffice for most uses I could see it having but on the flip side what is solvent like dcm that would create pressure and safely be placed in a canister hidden somewhere good... but this type of crap would be more inert than dcm im assuming and faster to evaporate but without any cooling effect (if thats possible)

Texium sent your thread to detritus because your aim was ill-defined and frankly, the idea looked like it was going nowhere.

I guess this is your second chance.

Volatile liquids squirt from pipettes and other similar equipment because of the high vapour pressure. This is even more pronounced with low BP solvents such as DCM because hand warmth brings it close to boiling.

Evaporation is endothermic so there will always be cooling.

Any low BP volatile liquid will have this property.

So...
What the hell are you trying to accomplish?
(This better be good. Because I too see a future for this scheme in detritus.}

How about something safer for the "secret squirter" novilty like a slowly dissolving carbonate like compressed baking soda, and a safe acid, like vitamin c. Using strong solvents is asking for fire/injuries

You seem to have (re)invented the aerosol can.
I'm pretty sure that evaporation without cooling is impossible.

Since we are in the realms of fantasy here, I might was well point out that compressed hydrogen gets warmer as it expands.

Someone here either wants to make a weapon, invent the spray can or that someone has a bigger issue with graffiti than I do.
The last one would be nice to hear.

I doubt that this would work even if your could find a solvent that had a low enough boiling point.

well DCM can cause a limb to fall off if you get it under your skin
i would keep DCM use on a very vague level and far away from any "fun"
difficult to even add anything to this thread as there seems to be no point in the device

Okay, now I'm curious, where do you get this from?
Did they do a rodent study injecting them subdermally with DCM?
Glad I'm not working with test animals..

Nope, it has unfortunately been observed directly in humans: https://pubs.acs.org/doi/10.1021/acscentsci.0c00100

There was another case I read about but can't find at the moment (likely the one Fantasma was referring to) in which someone PURPOSEFULLY injected their arm with a couple mL of DCM in order to demonstrate how "harmless" it was (hah!) and lost the arm.

Rather than moving this to Detritus, I added a warning to the top of the thread and moved it to Responsible Practices. Raising awareness of the hazards of DCM is important.

Holy shit, I didn't know that DCM can be that dangerous!

Once I accidentaly spilled some DCM on to my hand and little bit get under my watch, so it didn't evaporate. Just after a few seconds it started burning like hell. So yeah, DCM seems pretty harmless, but it isn't.

I’m pretty sure it’s DCM that’s in those Christmas lights that bubble. I had a string of them that all eventually burned out but I kept the little bubble tubes. I rigged up a 40W light bulb in a box with an opening in the top. I bound all the tubes together with a zip tie and set them in the opening. There they were, happily bubbling away on my work bench when I headed inside to go to bed. Next morning there were no tubes, just little shards of glass everywhere. I did finally find a couple of the tubes scattered around the shop. I guess the heat was too much and the pressure inside them got too high to contain. There’s a reason those Christmas light bubblers have such a small lamp in them.
