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.
You can’t claim you drank all day if you didn’t start early in the morning.

Fantastically speaking while in the realms of fantasy... pour it in a coffee mug and stick it in the ol' microwave. That'll get you a squirter.

DCM? Nasty stuff.
I do recall, that in the bad old days of 40 years ago, in an urban area. I saw a guy use a DCM based paint stripper, to strip an entire house
exterior of peeling paint. Just sprayed it on with an industrial-grade airless sprayer, let it sit for awhile, then he blew off the loosened paint
with a pressure washer. A little hand scraping fer fine tuning, and bingo! Thousands and thousands of dollars worth of prep work, done in a single
afternoon, with the aid of a highly toxic solvent.
To the best of my knowledge, no one ever voiced any objections to this operation.
Nowadays, I suppose this procedure would be considered somewhat more controversial.... If'n folks actually knew what was going on. One of the
problems with military service here in the USA. They tell you to man the burn pits; and you are supposed to follow orders. They tell you to spray a
housing compound with DCM stripper, then pressure wash it, sans protective equipment ; And hey! Orders are orders.

the first thing that came to mind when i heard "secret" squirter, was the idea of a lil paint stripper spraying device for covert graffiti like
messing with peoples cars.
in theory one might be able to put DCM in a can, though most cans assuming you went to the bother of refilling it, will probably explode after a while
since DCM swells and softens virtually all plastic, and the pressure will rip through the valve eventually, even PP bottles i have often warp after a
while.
Then also consider this; DCM doesnt strip paint alone. ammonia changes the charge of the surface causing things to unstick, much like how hydroxides
tend to be slippy on the skin while acids make you dry and grippy. DCM carries ammonia through your paint and causes delayering to occur by messing
with the charges responsible for adhesion occuring between unlike materials. Anyway, that ammonia isnt going to go in any pressurized vessel you can
scrounge up, let alone make. DCM in the eyes is bad but paint stripper in the eyes will actually burn you. it also wont be secret.
Im saying this to highlight the risks btw, incase someone is foolish enough to go and experiment with the idea unaware that most attempts to put that
liquid into a can all end with you being bathed in a mixture of liquids that blind you, suffocate you, give you cancer, and the fluids riding on the
shrapnel into your skin will cause mass necrosis without even having to penetrating through all the skin layers.
Anyway since the OP got deleted i dont know exactly what the deal was, but fun fact also about most hydrocarbons that boil real easy: they are
flammable as hell. hydrocarbon vapors, especially ones that like to throw off loads of fumes, tend to find ways to ignite.

The OP wasn’t deleted. The only context you’re missing was this thread in Detritus, which is hardly context at all: https://www.sciencemadness.org/whisper/viewthread.php?tid=15...
