Flexi-Sphere Interesting wire contraption that we played with as a child. A series of (4) tiers of overlapping and intertwined brass wire semicircular hoops are anchored at the open end to a pair of full circles. The whole can be shaped into a tube, double balls, a flower petal, etc, depending upon what areas are opened, which closed. A variety of colored beads on the hoops add a decorative touch. Fun, intriguing and decorative all at the same time.
