as a general rule if you see some “cool trick” on the internet that involves combining chlorine of any form (including bleach or tablets) with anything else, you shouldn’t do it because they are almost definitely trying to seriously hurt or kill people who don’t know any better. things like mixing bleach with other “household cleaning supplies” are especially huge red flags–it sounds harmless, but the chemicals in these things react to create extremely toxic gas, or worse

stuff like that almost universally comes from places like 4chan where it’s fun and cool to misinform people in the most dangerous possible ways, and it’s nothing short of evil that people use something as incredible as the internet to literally kill strangers for no reason
