Harvesting Capacitors for Backyard Munitions

Diabolus writes "This is the tale of a man, a bunch of disposable cameras, and his techniques for harvesting lots of capacitors to build a gauss gun. Insane..." A basic capacitor tutorial is probably in order.

Karma: Excellent
WTF?

Does this get rid of the karma cap? Or just make it hard to tell when you've hit it? I had ~38, and I'm now "excellent", so if I hit 50, will I be "Most Excellent"? (And then George Carlin will appear in a telephone booth to take me through time. "Party on dude!")

Yer an Anonymous Coward, you'll take it and LIKE it. Besides, it doesn't affect you, now, does it?

Use simple chemistry and a lot less effort!

Fill a can with a little bit of water and set it over a flame until the water begins to boil. At this point most of the air has left the can and been replaced with water vapor. The can will not implode yet, since the water vapor exerts about an atm of pressure on the inside of the can. However, if you submerge the can at this point in an ice bath, the vapor rapidly condenses and the can implodes by itself. Quite neat. You can make cans "jump" several feet once placed in the ice bath...
