Question

How long does an opened bottle of water last inside a car with the cap on?

Answer 1

However long you want, just it will get hot after awhile. Water doesn't go bad.

Answer 2

Unopened...forever, I guess.  It will eventually begin to taste like the plastic after a few months. Not recommended for drinking, then.

Answer 3

It Can Stay There For Atleast 8 Hours. But The Water Will Get Hot After A While. You Can Leave It There For How Long You Want But The Water Will Get Hot

Answer 4

days, weks, months. Does water have an expiration date?

Answer 5

It still lasts until the expiration date on the bottle, it just gets hot which is gross. Stick it in the refrigerator and it should be fine.
