        India rubber is elastic.
        [1913 Webster]
              Capable of being drawn out by force like a piece of
              elastic gum, and by its own elasticity returning,
              when the force is removed, to its former position.
        [1913 Webster]
     2. Able to return quickly to a former state or condition,
        after being depressed or overtaxed; having power to
