I’m not even sure why it exploded once.
As I was sitting at my desk last week, there was a small pop (maybe not quite so lous as popping open a beer can), and a couple of papers auddenly rustled. A second or two later, there was a loud BANG (somewhere between a firecracker and M80 but closer to the latter), and a soda can tipped over and a pen shot out from under a couple of papers and onto the floor.
After changing my underwear I investigated. A 9-volt battery had exploded; a Duracell Procell Alkaline to be specific. I believe it was lying on its side and both electrodes came into contact with the side of the soda can, and a currecnt resulted.
Some other known or unlnown items:
I dont know how long it took to run up to this.
The bottom of the battery away from the electrodes was blown out. I saw no sign of flame or smoke, didn’t even smell any odd chemical smell before or after. No liquid or powder came out. I’m sure I touched the body of the battery wthin 30 seconds of the blast, but it wasn’t hot.
Tell me, physicists and chemists, how and why this happened. Especially the second explosion.
Anyway, if you’re trapped by your enemies with a battery and soda can and need a distration, here you go.
