ELI5: Why is it that when it's cold out you can see your breath but not your farts?

Your large intestine is designed to absorb moisture before anything is released from your rectum. Your farts are dry. Your breath is loaded with moisture with nothing to absorb it.

Both are warm, but only one contains enough H2O to freeze visibly.
