Never using swimming pools after seeing this 🤢

The video likely worked due to its surprising and slightly unsettling premise, playing on common fears or curiosities about public swimming pools. The "life hack" format and the visual demonstration of a chemical reaction (fizzing tablet) also contribute to its shareability.

The video demonstrates a "life hack" related to swimming pools. It involves collecting pool water in a ziploc bag, adding salt and ice to it, freezing it, and then using a tablet that fizzes when wet to create a visual effect. The pool water is then poured into a glass, and its temperature is measured. Finally, the tablet is shown fizzing under running water and then being used to create a visual effect over the glass of pool water.
