trust me i'm in the same situation i need to know this stuff and dont have good acting classes. so i'm teaching myself too. but i already know how to do this one. trust me its easy, just only one weakness DONT WEAR CONTACTS WHILE YOURE DOING it IT BURNS!!! but i'm good at a lot of this kind of stuff. hey if you find out any more helpful things tho can u email them to me

1. think of bad things: death of someone u know, not getting the part, cutting your thumb off, etc. (this is the best)
2. eat onions or lemon juice befor e you KNOW you need to force cry
3. dont blink! whatever you do dont blink until it really hurts then you will start cryying automaticle
4. look sad. easily said
5. yawn

You ask for what most professional actors use but you do not want to read about feeling what the character feels. Most good actors trigger their tears with reacting to the situation set up for the character in the scene.

I can cry anytime I want but that is because tears have always been accessible to me. If I ever have trouble I remember the smells in the hospital room when my father died.

Remembering smells of a heart rendering situation of the past will almost always work. The sense of smell is hard wired directly into our emotions, more so than other senses because it is more primative.

It is also helpful to refrain from blinking for a while as the eyes quickly dry out and tears form to moisten them.
