It's a well known fact that stupid attention whore cum-guzzlers are more buoyant than real women with integrity.
there is really only one way to test this.
stand in something that is able to be filled with water atleast up to your waist.
create hypothesis as to wheather or not twig and berries will float. guesstimate as to perhaps why or why not.
fill slowly with water paying particular attention to when said water begins to reach the height of your peener.
and perhaps profit goes in there somewhere.
