This is why it's a good thing that I never went to electrical trade school.

I'll save you 15 minutes:

Dude charges up giant capacitors, verbally wanks about lots of volts, watts and amperes, compares his many volts and amperes to a thunderbolt and wanks some more, dumps the energy into a speaker, blows the speaker.

Visual amazement: not much, even in slomo
Lesson learned: overpowered stuff goes bang
Coolness factor: do you like big caps, lots of watts and lots of amperes? Then none.
