ELI5 Saturn - does it really rain diamonds?

ELI5 Explain Like I'm 5: Bite sized answers to stuff you should know about - in a mini podcast

Is it true that the temperature on Saturn is hot enough for it to rain diamonds. How can this be when the planet’s so far out from the sun? And how can this be given that Saturn is a gas planet? Why does Saturn have a Hexagon on its North Pole? Why are Saturn's rings almost perfectly flat and flush with each other?

... we explain like I'm five
