I do not think you can name many great inventions that have been made by married men

Imagination is more important than knowledge.
Did you turn the can upside down?
That’s not how you use compressed air…
don’t do this on circuitry please
Turn the can upside down and spray, it’s not the plastic, it’s the chemical inside the can, freezes instantly

Has nobody done this before? It does that on every surface…
That ain’t compressed air, that is r152a. It is a non flammable gas with a vapor pressure of around 60 if I remember correctly. What is happening here is that OP just tilted the can, resulting in some liquid to spray out, which cools down the keys on the keyboard, causing frost to form on it.
Don’t tilt the can, this isn’t compressed air
You don’t even need plastic. Just turn that compressed air upside down and blow it on anything!
But maybe not another human. My twin brother and I tortured each other with a primed upside down can of compressed air.
Not even mildly interesting
What is happening?
Besides the point that you shouldn’t be doing that, this is a physical reaction, not chemical…
Does anyone else notice a lot of posts on /r/chemicalreactiongifs aren’t chemical reactions? Phase changes aren’t chemical reactions I believe.
For anybody that comes along wondering what the thing is they’re spraying onto, it’s a r/mechanicalkeyboards with the keycaps removed.

“Feels like I’m walkin on sunshine!”
this kills the keyboard
edit: for clarification, getting that propellant in the keyswitch can strip the lubricant in it at best and at worst like u/Kapao said, getting it on the PCB would be *not good*.
Because your tilting the can
Wow
So cool!!!!!!!
Said nobody ever
I accidentally did this a few weeks ago trying to clean out my keyboard, and freaked out thinking I did lasting damage. Thank god there was none.
Is water condensing on a cold surface worthy of this sub now?
Jesus.

I press each button and use an air blower to blow the dirt out, works for me.
Even cooler when you shoot your friend in the ass with it and give them a forever reminder of your friendship with frostbite, and then get yelled at by their wife and permanently banished from their household.
Good times.
I literally got a 2nd degree (freeze) burn from this
took me three rewinds to know what’s going on lol
We used to call it unnatural ice.
It’s not just on plastic, if you keep at it (spraying I mean) eventually it will become liquid and “freeze” whatever it was on
You can tell it’s neat because of the way it is.
MX blue is the best switch
Yes, dry ice, what aboot it?
It’s a physical reaction not a chemical reaction, it’s not compressed air because you’re not reading the instructions on the can and using it properly, and it doesn’t just happen on plastic…
I think this post might have to go in a record book somewhere
