A cool guide about Rain on different worlds

Damn. If there was a planet that rained oil, I'm sure the US would have taken it over by now.
- Not a planet, but titan has hydrocarbons.
  
  Give it some time and maybe space fracking will be profitable enough to make Titan worth going after. Set up a couple liquifying stations in orbit and ship it back home.
- Needs too much setup
  The whole point of the oil is that a lot of it is all hydrocarboned together into these long chains and loops that bust open real energetically. It's big and energy dense so it's hard to produce naturally without a lot of existing chemical energy to store and pack together and then condense over geologic time. I don't think it's gonna come together for you in the clouds whatever you do to your atmosphere.
  Titan has lakes of liquid hydrocarbons though. Simple stuff like ethane and propane. If we could get the propane cars going mainstream, we could try to talk them into going out there and scooping it up for them; I think there's a fuck of a lot of it.
  
  I think I'd prefer leaving Titan's hydrocarbons on Titan, considering Earth's relationship with them so far.

How the hell do you get iron rain. Is there iron perspiration and iron clouds? Wiki says nothing. Super interesting though, I wonder how it would work.
- Iron melts. You didn't question the diamonds?!?
  
  Diamond scarcity is propaganda controlled by zales to monopolize the diamond market and up charge more than they're actually worth. They're everywhere, it literally rains diamonds on Neptune. Nothing to see here.
- The source for that seems to be this. This is what it says:
  Intriguingly, the temperature of OGLE-TR-56b's upper atmosphere is theoretically just right to form clouds, not of water vapor, but of iron atoms. Earlier this year, astronomers reported evidence for iron rain on brown dwarfs. However, such storms only occur over a short portion of a brown dwarf's lifetime, while the newly discovered 4 billion year-old OGLE-TR-56b should still be experiencing this exotic weather, thanks to strong heating from the nearby star.

Would you kindly keep this reposted drivel where it belongs?

5/6 of those will get you banned from the strip club.

glass and diamonds are solids; precipitation but not rain
- Depends on the temperature, and the pressure.
  Under enough pressure you can actually get liquid diamond.
  
  But is it in the tetrahedral geometry that characterizes diamond? Cause otherwise it's just liquid carbon.
