I don't see why these kinds of things are considered "challenges" when people are too stupid to know that they're dangerous. It's not really a challenge as much as it is retardation.
Let the idiots get hurt doing this bullshit. Maybe it'll teach them to not do dumb shit because someone on TikTok told them to. We shouldn't have to tell anyone of any age that eating detergent and falling on their heads are bad things to do, so if a person of any age doesn't have the common sense to understand that, they deserve whatever happens to them. I was a dumbass as a kid, but even I knew better than this.
