I cut any deflated ball up and reuse it... My most used idea is as jar openers and cushions for a wrench to protect the surface being wrenched...Also cut in a circle big enough to fit under your bowl on the table to keep it steady while mixing... Great as a shower head helper for tightening or loosening...Pieces can be used as a hole cover in pots... Pieces can be used with a glue or epoxy as a patch... You can even cut shapes and use as drawer pulls..(saw a man use rubber shapes on TV)
