Yikes, I just checked, and Captain Morgan's is 35% Alcohol. I'm aware of Bacardi 151 (75.5% alcohol) which is like fire water to me. Can't imagine drinking something so concentrated regularly.

The only reason I'd ever buy everclear (95% ethanol) is for cleaning optics.

In my high school days, we used it for Jell-O shots and drunk watermelons. Probably should have used vodka but ever clear was more bang/buck. I remember taking a shot of it once as a group “dare” type situation. It was as awful as you would guess

Good solvent for shellac as well, without the nasty smell and headache from denatured alcohol fumes. Costs more though, since it’s sold and taxed for consumption.

I can't practically get everclear since I live in California, where it's illegal. I use 99% IPA for shellac, it's not denatured but you wouldn't want to drink it anyway.

Before my brain caught up I was just about to ask you what brewery is it that can do a 99% Indian Pale Ale...

Stock up if you're ever in Oregon, Arizona, or Utah. No luck in Nevada either.

How about a hops extract?

I have experienced nitrogen narcosis before. It was like getting drunk very fast, including the room spinning. I hugged myself and ascended maybe 2-4m above the rest of the group and got back to normal pretty quickly after that and was able to continue to the dive.

What is the significance of hugging yourself in that situation?

Hugging yourself is a way to overcome the vertigo effects and associated nausea that can happen underwater. I’m actually not sure if it works on land!

> My issue, though, is i can't find a way to safely generate oxygen for a decent price. Depends on the definition of generate and decent price , but you can buy stationary medical oxygen concentrator for $1000, portable for $3000. If you want something easier you can buy pre-filled bottles or refill existing bottles at industrial gas supply places. If you want more, you can get a concentrator setup which small privat…

$1000-$3000 isn't decent for my use case; basically i want to use oxygen instead of ibuprofen for minor aches, coupled with heat or cooling. I find that pure oxygen does wonders for minor headaches and neck pain that i experience. $15-$25 a liter for oxygen is also not a decent price, relatively. At one point i found some concentrators that were ~$500, sadly i did not order and the brand name was alphabet soup; good…

$1000 is for brand-name. Used/imported are cheaper.

Refills of LOX are cheap, but you need to pay for the cylinder, which is expensive. At the end of the day you can get welding oxygen, which is exactly the same as medical/aviator. (And also you need to handle the cylinder safely)

Anyway, just start with Boost and see if it helps. They run out quickly, but nothing beats the convenience.

"We’re basically continuously narked, we’re just so used to it we don’t even know." Just because one direction on the gradient means that we respond in a way that looks like a narcotic does not mean that the other direction will respond in the opposite manner. I'm sure the nootropics folks would have discovered being super not high by now if it were as easy as breathing a mixture that doesn't have nitrogen in it.

as siblings commented, pure oxygen gets you high. a couple of breaths of pure oxygen will relieve pain and induce euphoria. I am not entirely clear on the definition of "narcotic" so i may be being redundant. My issue, though, is i can't find a way to safely generate oxygen for a decent price. I know electrolysis works, but these atomic sieves look safer. They're also difficult to acquire without a prescription, at l…

I don’t know if this applies on the surface, but divers don’t use pure oxygen on dives because of oxygen toxicity.

You already see this. Google "NFL oxygen masks". I'm sort of surprised I haven't heard about it in the context of shorter physical sports: I'd wonder what effect it would have on an 100m/200m/400m time or shotput distance to oxygen saturate like free divers do.

Elsewhere in the thread, someone claims that oxygen has a similar narcotic effect. Does the NFL use a helium-oxygen mixture, or pure oxygen?

I think an NFL lineup would be significantly less intimidating with their lungs full of helium. It's a pretty funny thing to imagine. (referring to the effect of helium on voices)

Sorry if this is pedantic, but we do actually use it for decompression, though usually no deeper than 20ft.

I've never drunk it. I don't like high proof alcohol.

Once I worked in a very informal lab and we were always looking for alternatives to buying industrial chemicals. I was working with optics, and Everclear came up as a good alternative to denatured alcohol or isopropyl alcohol. My friend who ran a microscope lab said it was pure enough to clean optics... however, since it was illegal to buy in California, we had a friend pick it up in Arizona and drop it off with us.

We put it in the flammable storage cabinet with a label saying it was 95% alcohol. Once during a lab inspection we tried to explain, but the inspector just said "yes, I went to college"
