An apparatus for permitting electrical connection between the exterior of an inflatable sports ball and electronics located inside the inflatable sports ball is provided. The apparatus comprises a support member, the support member having separate first and second through-holes provided therein for respectively connecting the exterior of the inflatable sports ball with the interior of the inflatable sports ball. An electrical connection port is located in the first through-hole of the support member for permitting an electrical connection to be made through the first through-hole. An air valve is located in the second through-hole of the support member, the air valve comprising an aperture for selective communication of air.

A pitch training ball includes a center portion, a first cap, and a second cap. The center portion is opaque and has a first planar surface at a first end thereof, and a second planar surface at a second end thereof opposite to the first end. The first cap portion has a first base that is adjacent to the first planar surface. The second cap portion has a second that is adjacent to the second planar surface. The first cap, the center portion, and the second cap cooperate to define a baseball shape. The first and second caps are transparent to translucent.

A reflective golf ball comprises a layer of silver having an average thickness ≥ 0.05 .Math.m and ≤ 0.5 .Math.m, notably deposited by reduction of a silvering solution, and a translucent, protective layer provided over the layer of silver.

An illuminated pickleball contains an elongated illuminated element with two opposing ends and comprises a shell that includes a plurality of apertures therethrough, two of which being designated as access aperture. The shell includes two opposing element holders which each include a shank projecting inwardly from the inside surface at one of the access apertures and which are mutually longitudinally aligned through a center point of the shell. Each holder is adapted for receiving the elongated illumination element and for retaining one of the opposing ends of the elongated illumination element by friction. When one end of the illumination element is inserted through an access aperture and then through one of the holders to engage the opposing holder, the opposing end of the elongated illumination element is retained, and the illumination element traverses through the center point of the shell and illuminates the pickleball from within.

As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The present disclosure provides for articles that exhibit structural colors through the use of an optical element, where structural colors are visible colors produced, at least in part, through optical effects. The optical element (e.g., a single layer reflector, a single layer filter, a multilayer reflector or a multilayer filter) can include the reflective layer(s), constituent layers, and an optional textured surface. The optical element has a minimum percent reflectance in a wavelength range within the wavelength range of about 380 to 625 nanometers. The optical element imparts a structural color that corresponds substantially to the range of wavelength range.
