Here's a couple of random GoPro videos:
A coworker gave me a case of V8 that expired in 2012. I couldn't think of anything better to do with it, so I shot it with .45 and .223. The GoPro was convenient to document the destruction because I didn't mind putting it on a tripod 5 feet from the target, where I would have been loathe to put my "real" HD video camera there.
