Does anybody know how long it will take for a 20 oz bottle of Pepsi (unopened) to explode if it is in a freezer? The bottle was about 70F when it was placed in the freezer, at about 12:30 pm EST. I will be returning home at about 7:30pm EST. As there is no way for me to go remove it, what do you all think will have happened to it? Oh, as to why it is in there. I was planning on leaving the house at 12:45 (which I did), but wanted a cold soda to drink at 3pm. I figured 15 min in the feeezer would be better than in the fridge. I forgot it when I left the house.
