Slingshot Vs. Coconuts

Thanks to F&S Senior Editor Colin Kearns, who alertly spotted Joerg the Slingshot Guy on youtube and informed me of his existence.

Joerg is obsessed with slingshots, to put it mildly, although that is not a bad thing. I get the feeling he lifts weights primarily to be in shape for pulling back surgical tubing. Joerg has a bunch of videos up on youtube showing his home-made slingshots (the self-defense slingshot complete with taser, tactical light and knife blades doesn't appear in this video, but it is worth searching for).

In this one he launches as 36-gram lead ball - about 1 ¼ ounces - out of his magnum slingshot, using a release. Will it penetrate a coconut?
