appropos of nothing: Coketron

[mhardy6647]

OK, so 1) I don't post over on the TV side much at all and 2) this is probably, at best, old hat (more likely, just irrelevant), but I just saw this looking for some info on 'magic eye' CRT's and thought I'd share.

Welcome back, AK.

In Peter A. Kellers book on page 24, the following info is to be found:
To illustrate the extremes in materials that have been used for CRT envelopes, almost every CRT lab has at one time or another fabricated a "Coketron" made from that one glass envelope that always seemed to be present in any lab, the Coca-Cola™ bottle. A little phosphor settled in the bottom and an electron gun sealed to the neck results in an operable CRT that never ceases to amuse lab visitors.
