Popping takes time, patience and practice. If you only have one snake, practice with him/her a few times and then give the snake a break. If you have multiple snakes, you can practice more often without irritating the snakes. Hatchlings are easiest as mentioned above as they do not have muscle control down there. Juvenile and adults are harder to pop but, if you practice and get the technique down, they can be popped with ease. I'm sure if you tell everyone where you're from, there will be someone close by that could help you out.
