LOL!! Boy, the stories I can tell you about accidentally shorting and blowing up capacitors while working on amplifiers and other equipment. A decent sized capacitor sounds like a gun going off when it pops.
On a more serious note, Capacitors are not meant for storing electricity on a long term basis. Yes, they charge quickly at high voltages but you're not going to run a car on a "charged capacitor."
This isn't "back to the future" and there's no such thing as a flux capacitor. Yet another "breakthrough battery scam" IMO.
Our activities were more about intended discharge, to illuminate photographic chemical reactions and record the event.
Many screwdrivers met their maker....
