Not to take the fun out of devising your own experiment, but the fine fluid dynamics physicists at the Splash Lab (at Brigham Young University) are trying to figure out how to prevent urinal splash-back right now! Fluid dynamics scientists (calling themselves the "wizz kids") set up a water tank and nozzles (emitting colored water) to mimic the natural ...


First, any fast moving stream of anything with mass is going to splatter when it hits something else -- it's really all about the angles (source & target) and velocity as to where it goes during the impact. Toilets are shaped differently, too, with some longer, shorter, taller, etc. You're potty training though -- not refining bathroom skills. Most ...


A few people have touched upon this (he says sarcastically) but the best way to reduce it is by sitting down. An increasing number of men are sitting when they use the toilet as it's supposed to be more hygienic (as there isn't urine all over the place). I beleive Sweden and Japan are a couple examples of this. Failing that, don't tell him where to aim, but ...


According to a recent study, the optimal way to reduce toilet splash (besides sitting down) is to: drop a few pieces of tissue into a toilet bowl to soften the blow. For a urinal: stand slightly to one side, and aim downwards at a low angle of impact


Bed wetting, even at 7 years old, is common. About 1 in 40 children at that age wet the bed. Children usually grow out of it. Stop waking her in the night. That doesn't help. Make sure she is drinking plenty in the day time. This will help her train her bladder. She should reduce the amount she drinks in the evenings. Make going to the loo last thing ...


My wife is the school nurse at an outdoor school (sixth grade camp) and this problem is very common among the sixth graders (10-11 year olds) she sees. They've developed procedures so these kids can attend successfully without the other kids knowing. As annoying as this is, it will pass. Adding shame, even unintentionally, will help nothing and hurt a lot. ...


anyone ever tried putting a mist of water inside the toilet bowl? Just a spray that starts when someone stands in front of it, maybe downward from the top of the back of the bowl under the rim. The droplets would knock down any splatter.


When aiming at the bowl instead of the water, note that the shape of the bowl makes a big difference. To be precise, a steeper angle of the surface being hit creates less splash-back. This is why anon's answer mentions "near the rim" - the sides of the bowl are the steepest. We're teaching our boys to sit down for any business, except in nature and in ...


First off, try to avoid forcing things as much as possible. If worst comes to worst, go back to diapers/pullups; we did this at one point, and survived. It is possible your child is simply not ready for potty training; some aren't at 3. More likely, though, going back temporarily would allow you to reset some of the issues - the 'battleground', so to ...


Ah potty training: the endless struggle. We found scheduling regular potty breaks helped with our 2.5 year old girl, because she did the same thing as your son. We tried to have roughly 6 schedules potty breaks throughout the day. Unfortunately, if your son is a human child then there is a 99% chance of this also becoming a battle ground. Our daughter did ...


Some urinals provide an aiming point:


Being a male and owning a penis for as long as I can remember, I have found that aiming here is most efficient for minimal ricocheting


My son was a bed wetter until he was 8 and his father and I split. I mean it stopped as soon as he left. Maybe stress?


It really should pass, however I know that the addition of shame can prolong and even make the issue worse. Waking her up with break up her sleep and make her more tired. My experience is that bedwetting is best solved with rewards and celebration of success. Ultimately if it continues to 10+years old there may be trauma that is contributing to the ...
