Actors: Make Yourself Cry On Cue

I'm about to give you the best technique to cry on set that you will ever learn (Unless you already learned it of course).  Have you ever wondered "How the hell does she make herself cry like that?" So realistic, no effort, looks like she was really crying right? WRONG! I've been on many sets and have talked to many directors and I have found the number 1 way that actors are using to cry on cue.
