Preventing Splashback

I don't know how often this happens to other people, but occasionally, when I poo, the toilet water splashes back and wets my ass a little. This bothers me, especially since I'm a mild germophobe.

So I was watching Olympic diving last year, and noticed that there was water being sprayed onto the diving surface, presumably to disrupt the surface tension of the water to minimize a diver's splash. Why can't this surface tension disrupter be added to my toilet? I don't think it adds much cost, and I think people would appreciate keeping their bums a bit drier.
