I've always said that I should play around with these HV experiments, but never seem to have gotten around to it! One day I'll really have to spend some time with this fun stuff.

Love the
scent of the produced Ozone! Has a distinct smell.
Very distinctive, isn't it? Maybe it's one reason why I always used to like riding on the London Underground when I was a kid. Down in the tubes the ozone contributed considerably to the distinctive odor of the network.

Then I grew up a little and discovered the same ozone produced by the corona from failing EHT insulation in a TV set. [Linked Image]
