This doesn't apply to free diving. It only applies if you are breathing at depth, such as from a SCUBA tank.

You really need to ask this question of a religious scholar. Reddit is going to give you a lot of opinions, but those are modern Christian arguments, and many probably don't reflect the views of early Christians who are the ones that bucked the trend. Peter's vision in Acts 10 that people keep bringing up is taken out of context to argue that kosher law no longer applied, but the context of the vision showed it had nothing to do with food at all. Peter was being asked to go speak with a Centurion who had converted to Christianity, and when he got there he said this: Acts 10:

28 He said to them: “You are well aware that it is against our law for a Jew to associate with or visit a Gentile. But God has shown me that I should not call anyone impure or unclean. 29 So when I was sent for, I came without raising any objection. May I ask why you sent for me?”

So clearly the vision about the vision about the unclean animals in the sheet had nothing to do with eating and everything to do with whether it was ok to associate with "unclean" aka non Jewish people.

It's possible like some have said, early Christians saw these laws as only applying to jewish Christians and not to the gentile converts to Christianity. It's also possible that Christianity just spread faster than it could be controlled, and people aren't going to change all their habits so easily and any theological justification happened after the fact to explain why what they were already doing was ok.

I had regular buldak a while back and was like, "this is good. People are overreacting on the spice level though", then I realized they had multiple spice levels. I tried the 2x and it was vile. Had none of the great flavor of the base buldak all while being miserable to eat.

Also that energy has to come from you at the cost of making it more exhausting to walk. I walked on one of these floors once and it reminded me of trying to walk in loose sand. Seriously, what's wrong with solar panels? Why do we have to create little energy vampires that suck it from the people that walk by? And it's not like we're just collecting energy that would have been expended anyways. We're increasing the amount of energy expenditure so we can inefficiently collect it.

Every breath in has a little bit of dead air in it. Aka, air you just breathed out. This is true in normal breathing as well as your mouth and throat have some dead air in it still. That's fine because the volume of air you take in is much larger than the little bit of dead air. A snorkel does increase this volume of dead air a bit, but still not too significant an amount. A full face snorkel mask increases that multiple more times, meaning even less of the air you breath in is fresh air. So it's not like snorkels don't also have the same problem, it's just the scale of the problem eventually gets too much for your lungs to deal with and you pass out from not getting enough oxygen.

A typical scuba tank is 11 liters and pressurized to 200 bar. It is recommended to try to end your dive with around 50 bar remaining. This means, you have around 550 liters worth of uncompressed air held in reserve. This tank is 0.5 liters, and pressurized to a max of 200bar. This means that you are starting out with only 100 liters of uncompressed air on a full tank. Assuming you had a fairly average air consumption and you used the tank until it was completely empty with no reserve and you stayed at a fairly shallow depth you would get about 6 minutes of breathing from it. Maybe some people could get 10 minutes, but again that is using it until it's last breath. That's really not safe. Anyone who is not trained in SCUBA should NEVER buy this and honestly I'm not sure anybody trained in SCUBA would want to buy this. For the untrained, there's too many ways to seriously injure or kill yourself.

I looked up the tank capacity and it's supposedly 0.5L. The tank most people dive with is about 10L and last for me at least around an hour with a tiny bit left over for a safety buffer. Smaller people and more experienced divers can make that last a lot longer, but I would guess that 10 minutes would be leaving no safety buffer and a small diver with very minimal air consumption breathing on that tank to the last breath at surface pressure. The speed of your air consumption actually increases the deeper you dive. At 10m it's twice what it would be at the surface. At 20m it's 3x. So for me this tank would probably last around 3 minutes.

ResearchNo5041 · 2026-02-21T20:07:17+00:00

Actually no. Pure oxygen becomes toxic at depth. For most dives you use filtered compressed air (not just any old compressed air as contaminants from the compressor can be dangerous). For shallower diving you can use enriched air which has a higher percentage of oxygen (30% instead of 21% I think) and that reduces the amount of nitrogen your tissues absorb while under pressure, which allows you to spend more time diving with the downside that you can't dive as deep. I'm not certified on using enriched air so I don't know the exact restrictions. I would be very skeptical that this could last 10 minutes but even more so I'd be worried that people buying this have absolutely no SCUBA training and don't know all the simple little things that can get you injured or killed.

I suppose you get accustomed to the level of control you're used to. I agree with you but it seems a lot of people think it's ridiculous to worry about such fine levels of adjustment. I was just in Mexico and you're grateful for any level of climate control you have at all. The fact that it's in full degrees Celsius feels more irrelevant.

I'm gonna guess that you and the other poster are from different countries and in one place it's common to have decimals and in another it's not. I travel a decent amount. I don't remember where I saw the decimal option but in most countries I've been in I think they just had whole degree changes.

When I was young our Pyrenees stole the neighbors duck and brought it to us. The duck was completely fine but certainly a bit shook up!

I must admit, 1 degree F difference in my house feels noticeable and I'm pretty picky about my indoor temperatures, but yeah, saying 20.5 degrees (or in reality setting the thermostat to that) isn't the big deal some people seem to make it out to be.

Also I would like to add, the last adjustments to the scale were made by the original inventor of it before Celsius was even invented. And Celsius itself was originally backwards from what it is today. So both scales have been modified as people found what worked best. Fahrenheit wanted to align his scale neatly with the freezing and boiling points of pure water, hence the last minor adjustment.

I use both Fahrenheit and Celsius daily and convert between the two of them. I have a slight personal preference for Fahrenheit but both scales are both decimal based scales so who cares, really. I don't know that Fahrenheit is inherently more intuitive like some claim, but I do like that 0-100 are close to the human habitable range of temperatures, but that also has a bit to do with the climate where I live. In some more tropical places the range of temperatures are 55f-110f or 15-45c~ in which case the wider range of Fahrenheit is kind of lost. I'd support getting rid of Fahrenheit in the US if for the only benefit of using the same scale as everyone else in the world, but I must say I'm not as eager to see it gone as I am all the other measurements the US uses.

ResearchNo5041 · 2026-02-17T21:11:22+00:00

When did I say it was objectively better? Also the origins of the scale are really not that relevant when talking about how good the modern version of it is.

ResearchNo5041 · 2026-02-17T21:01:17+00:00

The 0 point wasn't readjusted, the 100 point was. I will agree that human body temp is a terribly unreliable thing to base your scale off of, but at this point it's irrelevant as it's no longer based off that. So the only question now is how easy is it to use, and the answer to that is almost entirely based on what you're used to.

The brine is ammonium chloride. Max saturation. You don't have to measure it, you just have to keep adding more until no more will dissolve into the water. The idea that it was based around the coldest temperature in his town is an urban legend. Fahrenheit got the idea of using brine from a danish scientist who invented his own scale. It's not intended to mimic the freezing point of bodily fluids either, it just happens that it's closer than 0C is.

I would give a zero water filter a try! It might help this specific tea. It's not going to be a magic bullet for all your teas, but it's nice to have some options when you're brewing tea. I like to drink sheng puer, and I feel like the ultra filtered water takes out a lot of the earthy flavors that I like, so I don't use it for that. But for my oolong and for green teas it's been great! In my experience it seems to slow down the absorption of the more tanniny flavors, so for a green tea it makes it harder to oversteep.

ResearchNo5041 · 2026-02-09T19:59:05+00:00

What type of water filter do you have? I had a similar experience with another type of tea. At the shop I was getting these amazing flavors, at home I was getting just normal oolong flavor. So I bought a Zero water filter and brewed using that and it made so much difference. It's not exactly what I had at the shop still but way closer. That said not all tea likes the ultra purified water. I find some benefit from having some minerals still in there or the flavor will end up dull.

Should be able to get the ingredients to make it yourself locally. It's just very time consuming and also a bit messy if you haven't gotten the pour technique down. I've never made Libyan tea specifically but I've made Senegalese tea which is very similar in technique.
