Was there life on Earth before the Internet?  I can't seem to remember.
Vaguely recall staring at some kind of screen for hours on end, but there
was no keyboard. ;-)

Not for ballast tubes - they're supposed to have iron wire and be filled
with hydrogen, not a hard vacuum.  Not sure if the hydrogen needs to be hard
or regular.  I suppose you have to make sure there's no air mixed in it.
Dunno if it would blow up or fog up.
