This fellow puts 2000 volts through an LED. It doesn't last long.

They dont make resistors like they used to  :-)

couldnt he find an 82k  50 watt resistor in the drawer ?
With my mobile phone I can call people and talk to them -  how smart can you get ?

Isn't it tantalum caps that go bang hooked in reverse?

I find it harder to express logic in English than in Code.
Sometimes an example says more than many times as many words.

I thonk you must have missed out on some fun in your youth GoForSmoke :-) 

   Normal electrolytics used to make a great explosion, even now with the precut cross on the top they can still explode or make a hissing smoke stream as the can ruptures at the top.

In my youth it was KClO3, S and Al powder and once I had a kilo of Na metal. Later on I learned how much safer KClO4 and Al are. I don't compare exploding capacitors to any of those.
