Perfect for any budding filmmakers out there, is this video which shows you how to combine dry ice, soap, and water to create what looks like a planet with a strange atmosphere. I'm wondering why they didn't do this for old SF movies, as its certainly less sophisticated than CGI and more realistic than a painting.
The Trekkies making fan films should use this. Ditto for other fan film-makers &/or film-makers in general who can't afford a large budget.
A bump, because I saw this tweet that uses olive oil to make it appear that a beaker has disappeared. Again, this is one of those things that I'm surprised didn't get used more by SFX artists before we went all digital. https://twitter.com/gunsnrosesgirl3/status/1662472105353510913
