Oh Dear,
Asking for tutorials for pressure lmfao
If you wanna be a magician then you seriously need to sort yourself out you cant just go on a forum asking for people to post tutorials on youtube.
Your like a little kid thats wants to know how to do everything and dont care if they can perform it. Then they go make crap videos on youtube because they think their cool. Totaly runing effects.
I can just see you learning pressure then making a video on youtube and totaly ruining it.
actually, the problem has been solved.
