Fun with 2600 F Capacitors

I tripped across this youtube video and thought it was both entertaining and educational.

Wow!

I was told in college that Benjamin Franklin, in the early days of electricity work, would study stored energy in Leyden Jars (http://en.wikipedia.org/wiki/Leyden_jar); essentially some of the earliest supercapacitors. Franklin did not have the benefit of DMMs in those days, so apparently he would assess how much energy had been stored by electrocuting chickens.

Those supercaps store some serious energy.

Mark, that link doesn't work, should be: Leyden jar - Wikipedia, the free encyclopedia
When you said "earliest supercapacitors" I think you must have meant earliest capacitors, as a one pint leyden jar was apparently only one nano-farad. Although at the time I guess that was super .
