This is a crazy record, but Isaac from the United States is very satisfied with it. He officially has the largest mouth in the world.
He was beaten by another boy with a big mouth last year. But now Isaac has grown up and his mouth is open again. He can open more than 10 cm. It is precisely because of this that he can put all kinds of crazy things into it.
If your parents say you have a big mouth, you should show them this video.
