Heheh yes my point was simply that if anyone was inclined to use it they could.

I guess I'm not as funny as I think I am!

No, I got the joke; I was just supplying the parameters for the use of those thinking of building a Swiss suicide ball.

I understand the thinking about the stress points, but the "slit" I made is about 3/16." It more closely resembles a puncture wound than a drilled hole would. The string patch is actually a larger diameter than the injury to the ball and seems ideally designed to spread the stress out. A puncture wound, like you'd find with a nail in a tire, doesn't result in any lost material; you still have two edges to draw back together. With a drill hole, you have to fill a void and there's less for the string patch to hold onto. The proof for me was in the end product: the ball I made with the string-patched Exacto-knife wound holds air, but the one with the string- and rubber-patched drill hole didn't. That's just the way the alternative approaches played out for me; YMMV.

string patch, maybe I missed in the post but what exactly is it, do we need a certain type?

My experience with Pierre's instructions:

Most important lesson: inflate the ball first to check for leaks. There is no joy like the joy of discovering a defect in the ball after you've spent hours filling it with sand.

One other thought...What if you cut a tiny slit and then drilled tiny holes at the end of the slit. That would keep the "crack" from getting bigger. Works okay with metal what about rubber?

Can't say whether this would work or not (seems like it would help), but if you try it, definitely drill the holes first and then cut the slit between them (careful not to damage the "round" side of the hole). You'll never get a clean round hole at the end of an existing cut.
