looking for an incident that happened in original tv series

[Charles J. Louis]

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

The Voyage Home has the transparent aluminum scene with Scotty and McCoy.

I can't think of any references to liquid aluminum in Star Trek. Nor can Google, which returns results for transparent aluminum instead of liquid aluminum even with 'liquid aluminum' as the search term.

YouTube, however, has some videos of people pouring molten aluminum into a watermelon, a pool, and a fire ant colony. The fire ant colony is the best one with the best resulting sculpture. Having had a home in Florida, I enjoy watching the payback for my experiences with fire ants.

"Transparent aluminum" was first mentioned in the movie Star Trek IV: The Voyage Home (better known as The One with the Whales). There was never any mention of liquid aluminum (or transparent aluminum, or aluminum foil for that matter) in any episode of the original TV series.
