To expound on the Coke can, a friend of mine had a commemorative Braves can of Coke, from their only title. He had it sitting on the shelf of his computer desk. This is like 20 years later. He had left his back curtains open on a window nearby. Got home, had just sat down to eat, heard a strange sound, next thing he knew, the damned thing exploded. Imagine trying to get 20 year old Coke out of everything within 10 feet, including the back of your head. Also said he shat himself a little.
