CG>I have lucked into (?) an old monitor tube, aka TV tube. It looks

  Chris, be VERY CAREFUL! The vaccuum in those tubes can fling harmful
  bits of glass far and wide in a tremendous implosion.
  Having said that, look at the back of the tube, at the very end of the
  neck. If all the other stuff has been removed, you'll see a tiny pip
  of glass. (This was where the air was drawn out.) With the tube face
  down on some absorbent material, while you are wearing safety glasses,
  take wire cutters and snip that nipple off. You should hear an
  immediate adrenaline-jolting hiss as air rushes in. The hissing will
  continue for about 5 minutes. I'd also wrap the tube in a quilt,
  exposing only the neck. My hubby, who has snipped dozens of them, has
  never seen one implode, but there's always the first time, especially
  if a tiny piece of glass gets sucked in and hits the front of the tube
  from inside.
  There is also a screen (mask) inside the pix tube. Removing it would
  require cutting the neck off and fishing it out, piece by piece. Hubby
  doen't think the rare earth phosphers coating the inside will hurt
  plants, but he's no botanist. :-)
  There are much easier ways to make terrariums, but if you insist...
  good fortune to you! :-)
