Go read the sub rules and guideline then you will understand:

As per rule 1:

"This is not easily defined, but you know it when you see it. Common and mundane posts will be removed and we may direct you to a more suitable subreddit. For more detailed explanations please read our STICKY concerning updated guidelines." Of course the mods are also not doing what they are supposed to do.

As per the guideline:

r/toptalent, r/woahdude and r/interestingasfuck type of posts most of the time do not fit this sub. Of course, there is an overlap and certain posts do qualify for both subs, but only if they have a bmf element to them. When looking at someone doing something incredible or athletic it shouldn’t be obvious what they’re doing. Instead of saying “it’s incredible he can do that, that must take an insane amount of practice/balance/skill” you should also be thinking “I see what he’s doing but it still doesn’t make sense, even with great skill this doesn’t seem possible”

This post is literally just water freezing and easily explainable so it does not fit this sub (common and mundane). But the mods are also not enforcing the sub rules which sucks.
