Well, since no one really explained the clothes pin solution, I just had to try it myself. I have no idea if I placed the clothes pin correctly (and it's not really a clothes pin, it's a clothes hanger clip), but it gave me an idea of how this simple solution works. It's raining really hard right now, but at least I can see how it changes the flow of the water. It has potential.
Sorry for the fuzzy pic, but it's raining out there!
