I like that it comes in a can, not a plastic bottle simply because it gets colder faster and stays colder longer.

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.
