Please do not attempt this without being shown by someone who has performed it regularly. It has the potential to do some serious damage. Whatever you do, don't read something on a website and give it a shot - you have no way of knowing whether the person has any real insight into the effect.
Isaac, judging by your writing I would hazard a guess that you are quite young. If this is the case, please wait a few years before you try this.

Take care, Ian
