How much pee is in a pool?

This short science video is safe and genuinely educational for most kids, using a simple chemistry experiment to explain why pools smell the way they do. The content is age-appropriate and curiosity-driven, with the only mildly crude element being the frank (but scientifically relevant) discussion of urine — which is handled matter-of-factly rather than for shock value. It's the kind of video that might actually inspire kids to think more critically about everyday experiences.
