have you ever pointed with your lips?

I have. If you want to indicate something that may be in some direction, you could do it the hard way and raise your arm, extend your index finger, and say "over there, next to the flaming car". Or, you could do it like they do here. Turn your head in the direction of the flaming car, pretty much purse yer lips and kiss in the direction (without the *smack* noise, don't be silly), and say "por el carro en fuego". try it, it's kind of fun (flaming anything is unneccessary).
