Well, I mean no...it doesn't have to do with the water so much as the motion you use to skip a rock, you use the same motion to throw a Frisbee so that it floats in the air the way the rocks do each time they bounce, know what I mean? Wow, I'm bad at this haha. I'm sorry.
Yeah, that'd be easy to do except it'd probably hurt like a bitch to get hit with it, is the only thing...
