He's probably 11 or 12 in reality, I've seen alot of kids around that age looking about that size.
The only thing that really surprises me is the fact he can do all this with such small hands. Granted I didn't watch the whole video so I don't know if they zoom in on his hands more, but that's the only impressing part to me...
Yeah, he looks a little older than 8 until they zoom in. His face still has that chubbiness. I'd say at most he's 10.
And, what makes his hands even more surprising, they're kinda chubby fingers too! That's what surprised me!
