Curing your sling

 No, not like a ham with salts.  Sling curing involves a massive round object and a gravitational field that approaches 1 G.  Luckily we live on a planet with such a field and massive round objects abound.  However for the simple reason that all of my earthly possessions were scattered and stuffed into ten large bags due to a move, I couldn't find a single ball of any kind. In these cases one finds truly that duct tape applications have no bounds.  Thank you Scotch Tape
