There are posts going around the net about using pool shock to purify your drinking water. Those who trust these "internet chemists" might be playing with fire. Sure, there are sanitizing agents in pool shock. Duh. But pool shock was never intended for human consumption. Who knows what else the manufacturer put in their proprietary formulations - it was never even remotely considered for human consumption, so there is no required food labeling to tell you exactly what's in it. And every manufacturer, every product may be different.

Am I supposed to go out to my hot tub and grab the "pH Up" and "pH Down" chemicals for my upset stomach too? Maybe spray my frying pan with WD-40 so food won't stick?

Unfortunately, after this pandemic is over, we'll have fewer people in this world. Might as well let the ones who end up going be Darwin picks.
