human hand does not float
but maybe this can
(bone hand)
the hand came from a old project of mine that i did wile in 3d design class
but the hand was frozen and immovable
so i use bone technology
by putting a bone structure i was able to move the parts without destroying it's structure
this made me shape out the hands in a scoop shape.

(mesh hand)
i started out with a rectangle then sculpted out the fingers and the thumbs to the correct length.
made some minor adjustment.
apple a smooth effect to make the hand smoother.
