I put it in my bathtub and it sank to the bottom in about three hours. I'm
not going to use it though, we had to saw off the end for it to fit, and you
can smell a strong odor where it is freshly sawn. I figure anything that
catches fire that easity can't be good. Thanks folks.

It will be fine except it will float...it will never sink no matter
what you do to it.
