You'll get the hang of it in no time. I remember that I was a bit apprehensive my first time, but after you do a couple dozen it'll be no problem.

Start with a young snake, they pop easiest. As for the technique, it sounds like you've seen a lot of vids so maybe you are ready to give it a try.

The only things I would add are make sure your hands are clean and nails trimmed. I also use a horizontal rolling motion with my popping thumb, rather than having it the same direction as the thumb on the ventral scale.

Let me explain that again.

I like to have my thumbs perpendicular (90 degrees) to one another. One is in line with the vent, and pressing down on top of the ventral scale. This thumb is parallel to the snakes body. My other thumb I take perpendicular to the snake and roll up from the base of the tail. I have found this to be easiest, but it's just my personal preference. You'll find your own best way!
