Happy Father's Day. This is a useful little trick to stow away in your Zombie Apocalypse file. You can freeze stuff down to 40 degrees below zero (either C or F) with a can of duster. It's also great for testing elecrical components and super freezing your buddy's beer.

    How’s it going man,I had a question? Can I use any Air duster? My bearing has almost like needle leds in side of them,they almost look like the top of a pencil. If I spray the air duster would it damage it? Can I spray the out part of it?

    What effect does this have on the I.D. of the part?

    coolant bypass tube that runs along the top of lower intake manifold is a press in friction fit it has a few pinhole leaks…will the method help remove/replace?

    Although I did eventually use a freezer, I wish I would have considered this when I tried to install a CV axle transmission seal. I always knew the assemblers and mechanics had a trick up their sleeves; I just didn't know what it was. Thanks; I've got one more CV axle seal to go. Having stated that, I realize the glass-transition point of rubber is -40 degC, so I cannot go too far without risking the destruction of the part. Perhaps I can heat the transmission up with a parabolic room heater, increasing the temperature differential as well.

    You are the confuser….what is the product

    The cooling spray has gotten so damn pricey now and not as cool as before (guess it's a new less harmful composition) so I just turned a propane bottle upside down. You just have to have good ventilation so you don't blow your house up.

    When I was a scumbag in highschool I used to steal the freezing chewing gum removal spray from the janitor closets.

    Why does it have to be up-side-down?

    thank you🙏

    will this hurt the molecular/ structure of the part?
    Is it 100% harmless? thanks
