How do bottle rockets fly?

Bottle rockets are rockets made out of bottles.When you put eno and vinegar in the bottle it creates carbon dioxide, which creates pressure that makes the bottle fly.

Now we put seven spoons of eno in the bottle and some vinegar then it creates carbon dioxide and the pressure forces the lid open  and the rocket blasts off.

That is what makes a bottle rocket fly.
