Okay, I admit that this is a bit, err, gross, but I am truly interested in the physics behind the phenomenon, and am hoping I can get some (serious) opinions... Okay, so the previous owners of my house were older folks who installed a commercial/handicapped style toilet in one of the bathrooms. It has a larger bowl than the average home toilet, and it has a more gentle curve that makes the "banks" around the waterline a bit less steep. The toilet also has recently developed a slight leak, causing tiny streams of water to flow from numerous points around the bowl. There's the background. The fun starts when I dump the clippings from my electric razor into the bowl. The tiny clippings tend to gravitate towards the edges of the waterline, and in the places where the leaks flow down to the water level, clippings will actually move upstream, and climb an inch or so up the bowl! Frequently the clippings will also quickly rise and fall in the stream as if trapped in a sort of elongated whirlpool. It's weird. I'm guessing that this may happen due to the effects of water surface tension. I'm thinking that perhaps that as the small streams of water running down the sides of the bowl reach the 'pool,' the surface tension of the pool denies entry to some of the stream, which gets deflected *backwards* upstream, and can carry some of the little clippings with it. Okay, all toilet humor aside, can anyone (physics majors?) offer me an explanation for this strange phenomenon?
