You’re right, the pressure gauge shouldn’t change without a leak or temperature change (Boyle’s Law and such). But it’s hard to have a 100%, no-leak extinguisher. There’s plenty of points of failure to keep the thing pressurized, and the leak could be imperceptible (over months) or a rapid failure
And you wanna keep contents from settling as well, so you don’t just spray gas when trying to use it. So you mix it a bit and inspect the gauge every so often, because you don’t want it to fail when you need it most
Ideally, it shouldn’t lose pressure. But also ideally, you don’t have a fire that requires an extinguisher in the first place
But yes, you’re right on that one. “Settling” of the fire-retardent wouldn’t cause a pressure change. It’s just part of the safety inspection to check the gauge as well as to “mix” it… keeping it ready to go
I always right-clicked for the “more info” (or whatever it was) with any suspicious email. It would look like a bunch of html code that I didn’t really understand, but buried in there would be a company name that was usually obvious, like “phishtesting.com” or some bullshit.
I always had a 100% report rate, and always joked that I was waiting to get a prize for my accuracy. And obviously, also a joke to ever think I would get anything for it
I find it hard to use IMDb ratings as a metric for picking a good horror movie. The scores sometimes seem like they’re just all over the place, when looking at the horror genre. I just watch a trailer, maybe read about it a little, and check it out myself. I would’ve missed a ton of good horror flicks if I had gone with ratings alone
No GPS, no map Quest, no internet on cell-phone. You just got lost in the smokey mountains for hours, about to run out of gas, hoping there was an open gas station at the next exit. Just raw-dogging those road-trips for the most part
