As cold or colder than ice cold, but still in liquid form?
Also, does the temperature of ice decrease coordinately with the surrounding air temperature? Basically, how cold can ice get?
Maybe I should know these things. I wanted to give someone who already knows the answer a chance to boast instead of gewgling it.
I really just want to be able to drink a glass of water that is twice as cold as any water I've ever had. Thank you.

I don't know for sure, gut feeling is that it probably can but it would have to be at a different pressure.
Pretty sure drinking anything that cold would hurt.

Yes. The trick is being able to drink it without disturbing it..how I don't know.

pressure changes the boiling point, not actually sure if it affects the freezing point tho. possibly does. adding a little salt would but to still be drinkable, then not by much.

also to drink water at a diffrent pressure you'd have to be in a pressure chamber at that pressure. else it would freeze again the moment you took it out of pressure.

Why would the water be colder but still liquid under a different pressure?

You can supercool it like you can superheat it, cant you?
You know like when you put it in the microwave and it doesn't boil til you chuck something in it can nucleate around.
I think you can do the same, but with chilling it and then when you disturb it it all freezes.

The higher the salinity of the water the lower the temperature that it freezes at, though you wouldn’t be able to drink it.
The temperature of ice can be at absolute zero which is the lowest temperature possible.

OK so what's the super easy home made pressure changer model? I'm fasting from liquid until I can create this.
Really though, what would be the most realistic route a layman such as myself would go about in pursuit of drinking a 2x as cold water? Is there a science lab or research institute nearby that might be able to assist me? Would it be expensive? Is it even really feasible?

Add anti-freeze to it. I'm pretty sure it's only toxic for dogs.

It's also possible to supercool pure water at standard pressure if there are no nucleation sites within the liquid from which spontaneous crystallization can occur, and if it's cooled rapidly enough (like from room temperature to -130 degrees C within milliseconds). Look up amorphous ice.

i think thats whats happening in ao's video.
