This video is safe for most school-age kids and is genuinely educational, using real science to answer a question kids already wonder about. The gross-out factor is the whole point, but it's handled with curiosity and humor rather than shock value, making it a surprisingly solid introduction to chemistry, measurement, and public health.
No realistic violence or threats appear in this video; the sound effects at the end (bomb explosion, gun firing, glass breaking) appear to be comedic/stylized outro sound effects rather than any realistic depiction of violence.
No toxic behavior modeling is present; the video explicitly discourages peeing in pools ('be cool and don't pee in the pool') and frames the science as a reason to adopt better behavior.
The comedic sound-effect montage at the video's end (bomb, gun, glass breaking, cheering) appears to be a lighthearted stylized outro rather than any meaningful playful violence sequence, and no gameplay or fantasy combat is present.
This Mark Rober-style science video investigates how much urine ends up in swimming pools using a clever real-world chemistry method developed by a university researcher. Kids will learn about mass spectrometry, chemical tracers, and how chlorine reacts with urine to form trichloramine — the actual source of that 'pool smell.' The subject matter is inherently potty-humor territory, but the tone stays scientific and informative throughout. There's a brief clip of someone on TV apparently drinking urine as a cultural reference, and the video ends with some sound effects (including a gunshot sound) that appear to be unrelated outro clips. The video actively encourages responsible behavior by telling viewers not to pee in the pool and explains the real health reasons why. There is no strong language, violence, or inappropriate content — just urine discussed in a clinical, educational context.
Knowledge is power! Even if that knowledge causes you to rethink some of those lovely summer memories.

We looked at some samples from some pools in my area to determine how much pee was in them and I conducted an experiment of my own to see what was the cause of that "classic pool smell". I also presented average amounts of pee in large pools as well as an equation to determine how much pee is in your own pool.

We recommend this video for kids 8 and older. The content is educational and science-focused, but the subject matter — urine in pools, trichloramine, and a brief mention of drinking urine as a cultural practice — is best suited for kids who can engage with it in a mature, curious way rather than just as gross-out humor.
No strong or crude language is used. The word 'pee' and 'urine' are used frequently in a clinical, scientific context. There is a very brief TV clip referencing drinking urine as a cultural practice, which some parents may want to address with younger children.
It's genuinely educational. The video collaborates with a real University of Alberta researcher and references published studies from Purdue University, explaining concepts like mass spectrometry, chemical tracers, and the chemistry of chlorine byproducts in an accessible way.
Quite the opposite — the video explicitly and repeatedly encourages kids not to pee in the pool, and explains the real health reasons why (eye irritation, asthma risk from trichloramine). It models scientific curiosity and responsible behavior.
The video ends with a brief montage of sound effects including what sounds like a gunshot, glass breaking, and crowd noise, which appear to be unrelated outro clips. These are very brief and not graphic, but parents of sensitive younger children should be aware.
The video briefly shows several packaged food and drink products while explaining which foods contain artificial sweeteners, but this appears to be for educational illustration rather than paid promotion. There are no explicit sponsorship disclosures in the transcript.
