The bottle cap challenge has kind of blown up on Facebook (and elsewhere). If you're not familiar with it, here it is: Bottle Cap Challenge: Why John Mayer, Jason Statham and others are doing it - CNN I've seen a variety of reactions to it, ranging from "That takes skill! I couldn't do that!" to "that's cool I guess" to "that's so dumb, MA is all about POWER... they should be destroying that bottle, not knocking the cap off!" I generally don't care about social media challenges (although it's super cool that the ice bucket challenge actually raised a ton of money for ALS research), but I'm surprised by some of the negative remarks. I mean, one guy actually made a video of himself kicking a water bottle into oblivion and telling the viewers to stop kicking bottle caps and get back to real karate. You really have to be annoyed to go through all of that effort. Any thoughts?
