Oil & Water

Just because I have seen a plane being flown and even though I know a airline pilot and even when a Leer Jet was hired for me, not once have I thought I knew how to fly a plane. So why do I think I can do perfect droplet shots? I've tried this once before and wasn't happy then and now the best I can do is a glass phallus - the one in extras is even more rude. This one is with oil ......again I'd heard this was something you did, the extra is without.
