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 ...

My nine year old boy constantly had soap in his hair after showering, despite being in there long enough to rinse Chewbacca (of Star Wars fame) thoroughly. We installed a hand held shower head (so he could get it right up close to his head,) and it solved the problem. This might work for you too, since your daughter will be able have enough control to rinse ...

I do a body block by leaning across the baby's belly (without any weight being put on the baby) until I've got things cleaned up, up front. It also prevents the child rolling over and escaping the area where I am doing the changing. I can then move to a better angle for being certain I've got the back end fully cleaned up while knowing that at least the ...

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

First off, the doctor must wash his/her hands after entering the room, period. The doctor opened the door with his hand, right? That's a (major) point of contagion right there. Unless you're in some futuristic practice with automatic doors, I would never excuse the doctor from not washing post-entering the room. Second, unfortunately, doctor handwashing ...

NOTE: I'm not a pediatrician. Contact one for a professional evaluation of how much snot is too much. However: It's good for you to have some mucus in your nasal cavity: it keeps tissues lubricated, and traps dust and bacteria, preventing it from getting into your lungs (which are more sensitive). Too much snot prevents you from breathing well, and might ...

If he always has a runny nose, have you thought of taking him to a doctor? Clearly you have wondered if this is bad for him, or can cause problems. You're the adult here, and you're responsible for your child's health. It won't work to wait for your son to say, Hey, Dad? I have this constantly runny nose. Do you think you can take me to my Pediatrician ...

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.

We had similar problems, however not that regularly. What worked for us was saying something like "please keep your hands up until you are cleaned", but honestly I'm not sure at what age this worked. In case the baby still tries to move his hands into the dirty area, you could block them just for a short moment with your back of the hand or with your arm ...

Perhaps cleaning her hair without shampoo is a better match for her. There are many resources detailing methods to go "shampoo-free". Some involve water only, others involve a small amount of baking soda or other ingredients. In general, it takes about 2-6 weeks to make the transition, so good to make the change over a school break or other time period where ...

General problems and benefits (which apply equally to adults and children): Shower Chance to slip and fall (causing injury) Uneven distribution of water over body / having to step out of the water (not really a health risk, but can cause discomfort); this will depend on type of shower head, where the head points, height of the person, and size of the ...

I say, in a clear firm tone "please can you wash your hands before continuing?" If I wanted to be delicate I would say "Sorry, but I didn't see you wash your hands. Would you mind doing so before you continue? Thanks." In England it is always acceptable to remind clinicians about hand hygiene and patients are encouraged to do so. I would raise a ...

In my 11 year old daughter's class, none are even close to this stage. Of my wider group of friends, only one has a daughter that has started shaving her legs, but she had to start at about 8 - very early puberty for that one...has her mother's genes. From the UK's National Health Service guidance, Most girls will begin puberty at 8-14 years of age, ...

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 ...

One thing I want to bring out and focus on here is the specific elements of the question, "How do I get my son to blow his nose?", which seems to me the core of the question above. The answer: You largely need to let your son figure out for himself that he needs to learn to blow his nose (either figure out how to do it, or figure out how to ask for help), ...

Can not blowing your nose lead to a sinus infection or something? According to some articles available online, blowing your nose can actually lead to sinus infections, and possibly ear infections. Blowing your nose uses much higher pressures than coughing or sneezing, which may cause germs to be blown into your sinuses or your Eustachian tubes. Blowing ...

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

Don't have her wash her hair in the shower. Wash it at the sink or using a bowl instead, like at the hairdresser's. That way, your daughter can be fully clothed, or at least enough to respect her privacy. You could even make it a game, playing hairdresser, washing each others hair. By washing yours, she can see how much and how thorough she needs to rinse ...

I started shaving in 6th grade when the girl who sat next to me in gym pointed out to me my legs were hairy. My leg hair wasn't dark--it was quite blond, actually, but it was mortifying that a classmate had to point this out to me. It quickly dawned on me that I was probably one of the last girls in my substantial 6th grade class to start shaving my legs. ...

I would ask in a curious, not attacking way something like : "Don't you need to use these?" (pointing at the sanitizer) "I always thought doctors offices were really picky about those..."

A bath is a set temperature that will get cooler. You can test the temperature before you get in. A shower (depending on the plumbing) can get sudennly much hotter. This could cause scalding or the rapid movement away from the hot water could cause a fall and injury.

I can tell you if you want to stop your son or kids to take the longest shower ever... I have a hot water shut off system that I design and install... And how it works is that when your kids are in the shower you Control the hot water by a switch ... But it doesn't turn the water off it leaves the cold water on so they get a cold hit of cold shower ... ...
