You don't mean making the bottle fly
We play to make the cap fly
The way to play is like this:
First, put the cap on the bottle and tighten it!
Then you press the groove of the bottle to twist the bottle
to make it into a twist-like thing
Then, because of the strong pressure inside the bottle
you open the cap
the bottle will press the cap out and fly up high
But then you have to be fast when you are re-ninning the cap
otherwise it will leak (lol). I've had a little experience with it.
