If you wanted to go for authenticity with your fake-as-fuck video at least pick a real "juggling" art that has a documented history and not some lamo lord of the rings can o' cockshit.
What's so impressive about it imo is that it almost looks fake, and there are lots of yt comments that also think it is. But think about it: "faking" this would be significantly harder and involve just as much practice as just doing it.
