Why in Heaven would you or anyone want to do it? [I think there may be a

No troll, just a wild hair. I got to thinking of using mercury as the
conducting medium for an RF antenna switch and then wondered if mercury
could replace the upper part of a whip where there is low current and
high voltage. The mercury changing length in a thermometer triggered
these unthinkable thoughts. Imagine changing the current through a
resistor in order to tune an antenna by varying the mercury level.
No assumption here. I agree that this would be VERY difficult, although the
"upper part" sounds feasable. Just replace the screwdriver motor &
mechanism with a pump...
