Ah, just toss it in water and see which bits float.

Hmmm. I honestly can't remember if muscle development has been brought up. This
wouldn't be atrophy but it would share some aspects of it. It's doubtful it
would not facilitate the muscle development necessary for bipedal movement
on land.

I've asked him about the substrate of a body of water - loose pebbles, sand,
mud, etc that do not contribute to a firm foundation to walk on. He tends to
imose more conditions when such objections are brought up - like it has to
be flat, the water of a certain depth, and so forth.
