This is the baffling part. I live in a country that periodically grades the taste of regional water supplies, in addition to testing for solids and the usual. And I live in a part of that country consistently known for really great-tasting tap water.
It’s baffling that they’d sell water in a can. Please don’t tell me it’s bottled in Atlanta, where they bottle the worst-tasting coca-cola in the world, or it’ll be extra-baffling.
It’s only a dollar here and I like that it comes in a can, not a plastic bottle simply because it gets colder faster and stays colder longer.
That’s not how thermodynamics work. It’s either transferring heat more efficiently, or not. But always the same, in both directions.
Explain insulation and conduction.
If it feels colder in your hand, it means the opposite of what you assume: It absorbs heat from your hand faster, so the stays colder shorter.
Imagine instead you hold a perfectly insulated container. You could not feel wether the inside is hot or cold, or else the insulation would be faulty.
So if you really want to have a drink that stays colder longer, grab something which does not give away how cold it is, quite literally.
for… water.

Some people live in places where the tap water tastes like chemical asshole. Or they travel. Whatever the reason, buying water happens.
I mean, buying a bottle of water is at least a dollar too.
At the super market? I pay 0,29€ for 1,5l or 0,15€ for 0,5l.
If it is at a gas station 1$ seems really cheap though.
