Wingnut, that reminds me of a story.....
Back in the eighties we had a string of shootings on area freeways (Detroit, no surprise). Snipers were setting up on the overpasses and taking potshots at motorists. I was driving home from work one day when BANG! someone took a shot at my truck. As I sped off in fear, they shot at me again BANG!.
Turned out to be the six pack of PEPSI in the back seat that I had bought that morning. It was a real hot day and those cans were popp'n like bombs. For a minute there I thought I was the latest sniper victim. /w3tcompact/icons/mad.gif When the cans 'popped' they did not rupture. The aluminum just expanded in one quick instant to a distorted shape. They made one heck of a sound /w3tcompact/icons/crazy.gif
