We have been potty training our son. We got him comfortable going sitting down first, and now he is learning to urinate while standing.
What should I teach him to aim for when peeing while standing up, at the water, or at the side of the bowl?
I have always aimed for the water, but my wife just informed me, after 3 years of cleaning the toilets, that she noticed that sometimes there is splatter on the adjacent walls. Does aiming at the water create more splatter than aiming at the bowl?
I tried an experiment in the urinal at work today, and aiming at the bowl seemed to result in splatter also, but my theory is that at least the splatter from the water is diluted (or is pure toilet water), while the splatter from the bowl is at least 99% urine. I couldn't find much research, at least nothing I could take seriously. Is there any evidence to support either argument? I considered conducting an experiment to measure the splash, but having a hard time figuring out how to collect data.. maybe I could hang some sheets of paper around the bowl and look for spots. Any ideas?
