There have been a bunch of them to the same effect. A pint bag 
of anything you might consider won't realistically overcome a 
planetary atmosphere to keep a piano in tune without limiting 
the volume of that atmosphere.

That's easy. Since the piano needs to be hermetically sealed 
to make this work, pretty much anything, sealed in the bag 
with the piano, would not encourage the piano to go out of tune.
