It was a 160 uf 330 volt cap, and I did this when I was in the 11 th grade, quite an impressive amount of energy stored in something like that, it sounds like a pistol shot when you do it too. It came out of a disposable camera with a flash, the flashes are xenon and they use a simple solid state invertor to step up the 1.5 volts of a AA cell to several 100 volts stored in a 330 volt electrolytic cap, which is discharged into the flash tube when you hit the shutter.
