I tried doing that with a 4cx250 once. Never got it to work. Looking
back on it I should have mounted the base of the tube to the paint can
lid and hung it in the bucket upside down.
Hmmm, might be something fun to try this winter.

I recall an article on using a 4cx250 with water cooling. Actually it
sat upside down in a pool of water which was allowed to boil off from
the heat of the tube. Which means the tube didn't get hotter than 100
degrees C (until all the water boiled away). This is known as 'vapor
phase cooling'. Believe it or not you can cool a tube with STEAM!
