All electronics works on smoke.
If the smoke leaks out, it won't work...

;-) Reminds me of another joke I can't quite remember: something
dealing with the proof that electricity is really smoke....

A local (and now retired) engineering faculty member has an after-dinner
speech in which he "proves" that "electricity is black and heavy"!

For example, in an automobile, electricity is stored in the battery.
What color is the battery? Black!
And it is quite heavy for its size.

And on and on and on!

Sounds logical to me.

My favoite is the Dark Sucker Theory (light is the absence of dark, and
light bulds suck dark). Do a google on it for lots more info, probably more
than you ever wanted to know... :-)

And thusly another thread morphs far off topic...
