Question

Answer 1

Most quality volleyball's consist of three primary levels of construction.  The first level is a rubber bladder.  Essentially, this rubber bladder is the same material of a standard bike inner tube.  Usually the bladder is then either floating, partially attached or totally attached to a cloth layer.  This cloth layer is made out of material that looks much like cheese cloth and is sealed with a rubber like glue.  The outer most layer, shell, is made of leather panels, normally 18, which are glued to the the cloth layer.
