When buying used golf balls, keep in mind, some have rubber band centers (as mentioned in earlier comment), some are solid core (as you used), but some even have a liquid core which is under pressure and released when drilled into. I found this out a few years ago with a similar project. It can be messy and probably harmful too. I could find no way of knowing what the interior of the ball was made of by looking at it. Be safe.
