I think at the end of the video some guy asked on chat what would she do if she didn't caught it on time ( i.e. her boob/nipple). And she says she think she caught it each time but if she didn't she would cry some minutes. Then she add she would have to be more carefull next time. I'm not so...

For me it seems to be an epic "natural boobs" test fail. No matter how fresh they are, boobs move to the side when they're natural.
