Weather Proof Matches

I found this link and video to weather proof matches.  When I first read it, I thought they meant you could get the matches wet and they would still work.  Not the case, click to watch the video and see for yourself.

At one point he actually cleans off the wet dirt from the match and then it reignites.  I feel like that disrupts some law of physics, chemistry, thermodynamics, or something.  This could also be a disaster waiting to happen at a drunken college party or redneck wedding.
