86 of the adjacent bead and so on as shown in fig4 and 5 the engagement of the external walls 94 of the smaller end 84 of one bead with the internal walls 96 of the larger end 86 of an adjacent bead allows the plurality of beads to pivot and rotate with respect to adjacent beads to form a variety of shapes the shape of the cavity 78 formed in the large end 86 of the bead 76 is appropriately sized to tightly receive the smaller end 84 of an adjacent bead such that the beads 76 can rotate and pivot with respect to one another under the force of the user however the fit is sufficiently tight to create adequate friction to maintain the relative positions of the beads 76 once the flexible shower arm 64 is shaped by the user this flexible shower arm assembly 64 is described in more detail in u s pat no 5 865 378 the contents of which are hereby incorporated by reference it is contemplated however that any structure which allows for repeated flexible movement to a fixed final position and can accommodate the desired fluid transfer characteristics could be utilized for this purpose fig6 a b are an exploded view of a shower head assembly 30 according to one embodiment of the present invention as shown in fig6 a b the shower head assembly 30 is constructed using several layers of elements starting from the top of the shower head 40 the first layer is the upper portion 44 of the outer housing 42 of the shower head 40 the upper portion 44 has a shallow dome shaped top and an elongated portion 52 the elongated end 52 of.
