You know who else curtails developer choice by setting arbitrary deadlines and pushing for aggressive monetization? Game publishers. Pretty sure the devs don't want their game to be universally hated for lootboxes and bugs.

You'd need to go to a talk show and spew ridiculous fascist bullshit without laughing tho. Seems kinda hard.

The figure you've linked plots concentration by weight (wt.%), while the alcohol content of drinks is usually given in volume percent (v/v). Ethanol is less dense than water, so a 30% concentration by weight is a higher concentration by volume.

Imagine a 100g solution of 30wt.% alcohol. That means that 30g are ethanol and 70g are water. the 70g of water translate to 70ml volume (density 1g/ml) and the 30g of ethanol translate to 30/0.789 = 38.02ml. So in total, you would have 108.02ml of liquid and the concentration of ethanol by volume would be 38.02/108.02 = 35.2%.

Why it gets wacky at the end: Ethanol freezes at -114°C, water freezes at 0°C, but at specific concentrations, the eutectic composition, the solution freezes at a lower point than either of its constituents. The eutectic point is the lowest possible freezing point of a solution. The formula I gave is not applicable to eutectic solutions and is an approximation based on perfect solutions (which in reality don't really exist).

Whoops. Well, I forgot to account for sugar and other stuff which decrease freezing temperature as well, so the result might still be around right. It's an ok ballpark at least. Precisely calculating a solutions freezing temperature when it has that many different solubles is pretty hard.

You're right, I edited it.

Yeah, that's how it is here as well, so these Jägersicles look fake.

tl;dr Around -21°C (-9°F). Realistically probably a tad lower than that.

Formula for freezing point depression is:

ΔT~f~ = i * K~f~ * m

ΔT~f~ = freezing point depression in absolute degrees (C or K)

i = van 't Hoff factor, the number of particles the solutes splits into, ethanol does not split, so 1

K~f~ = freezing point suppression constant, for water 1.86°C * kg / mol

m = molality of the solution (aka how much you add), looked it up and it's 11.42 mol for 40% ethanol/water mixture

1 * 1.86 * 11.42 = 21.2412°C

In reality, Jägermeister is not a pure water/ethanol mixture and all that other stuff in there drops the freezing point by a bit as well. Ethanol is the biggest contributor tho. So maybe add 1° or 2° to this.


Is Jägermeister really that green in the US?

Did that once, cost me 30 bucks. Didn't see the sign, whoops. I did notice once it was too late tho.

Here is a scenario that actually happened, you'll be the judge:

Person A is someone who, to their own admission, wanted to be friends. I know them over persons B and C, long-time friends of mine, A is very close to C. I invite A to a BBQ at my place that B and C are attending as well, they leave me on read, but tell C they'll come, so when speaking to C shortly before the BBQ, I get told that A is coming as well. A then asks, last minute, if they can come too even tho I already know they planned to come. I brush it off as bad communication.

Next month, pretty much the same situation. I invite A, this time telling them that they should drop a yes/no so I can plan for food. Get left on read again. At the day before the BBQ, I ask again if they'll come, they say no. Next day, A asks if they could come despite saying no, okay well whatever. Anyway B and C arrive first and they know that A is coming too. They were told a week ago, I had no idea. Got me pissed, so I text A and ask what the fuck their deal is and now suddenly I am the clingy bad guy. B remains neutral, C takes the side of A telling me, it was my fault that it didn't work out and that A was simply trying to surprise me.

Anyway, I am not friends with C anymore either. Fuck that shit.

Where in OP’s post was this mentioned?

Nowhere, to be fair. The meme just struck a nerve with a past experience of mine and it hurt. My bad.

If getting messaged once a week or so to ask if you wanna hang is "smothering" and "risk pushing" you away, then maybe, just maybe, the problem is not the dude messaging.

It's not a tightrope walk, a friendship is built on mutual respect. Feeling left out and lonely because there is no reciprocation whatsoever is normal. Calling this OP's fault is extremely toxic, holy shit. If it's a tightrope walk, you didn't wanna be friends from the very beginning and are bad at communicating your intent.

But isn't minmaxing the fun out of your game to chase the 1% damage increase exactly what RPGs are about?
