Coke, battery, and phenomena
If this is not within the spirit of this sub then I apologize and can try to take it elsewhere.
I have several partially or fully empty and unopened coca cola cans. They were in a 24-pack cardboard box that I placed on the concrete floor of my garage next to a tractor battery. After 8 months, I went to bring the 24 pack inside and noticed that there was residue on the sides and bottom of the box, and the entire bottom row of coca cola cans were either fully empty or partially empty, but none of the cans had been breached and they could be squeezed to increase the air pressure in the can.
Any theories (or better yet, solid explanations) for how/why this occurred?
For the future, I'm not going to store coke near tractor batteries, but I'd love to know the science behind the phenomenon. Thanks so much!
