My only complaint is that he didn't put the string on TOP of his hands. this was kind of a dumb thing to do and ended up yanking his tooth sideways instead of straight up.
But, when he's old, he'll still be able to say that he had a tooth yanked by a rocket.
This will be an amazing story to tell for the rest of his life. This action has set in motion a long chain of events that will result in this kid getting promotions and the attentions of ladies/dudes.
