You should NEVER twist or snap your hand when throwing any pitch, including a curveball. That increases the stress on your elbow and shoulder and leads to significant injury issues. A proper curveball is accomplished with grip and angle of the hand position during a normal throwing motion. Please refer to any book or video by Tom House on this issue

I suppose you didn't read my instructable very carefully. I warned everyone who viewed my instructable about hurting yourself when throwing a curveball.

I read it; the way that you described how to throw the pitch is incorrect and will lead to injury regardless of how old you are. If you are throwing a curveball that way and do any significant amounts of pitching then you will have an injury eventually. That's why I pointed you to Tom House - the current pitching coach at USC, former pitching coach for the Houston Astros, Texas Rangers, San Diego Padres, and is well respected in baseball for his knowledge. A proper curveball is no more damaging than a fastball and little league players should still throw nothing but fastballs.

I know. I did hurt my arm, but my friend showed me how to throw the right way.
