Put the sponge in a ziploc bag or the bag your newspaper uses.  That would keep it dry.

lol, it seems usable but looks a bit bad, also I don't like the smell of inner tubes and how they make your hands smell, and lastly if it rains that sponge is going to be disastrous :) Tying things and other uses for inner tubes are a good idea though because it's a sturdy usable material and not expensive either if you were to use a new one.
