I have been searching for an incident, I'm pretty sure was in the original TV series. It is near the end of the episode where Kirk tells Spock, I believe, to give an earthman the formula for "liquid aluminum". I've seen much on the subject of "transparent aluminum" but I'm certain it was for "liquid aluminum". If this is familiar to anyone, please help. I've been searching for a while.
Thanks in advance, CJL
