A paintball fill material includes water, a humectant, a thickener, and a dye.

A fitness ball includes a ball portion having a generally spherical-shaped resilient shell, a pocket disposed in the ball portion and defining an opening in the ball portion, and a handle extending from a first point on an inner surface of the pocket to a second point on the inner surface of the pocket. In some embodiments, the fitness ball further includes an impact-absorbent filler material disposed in an inner cavity defined by the resilient shell and the pocket. In other embodiments, the fitness ball includes one or more gel inserts embedded in the pocket to cushion impact of a user's hand with the pocket. In other embodiments, the pocket is adhered to the resilient shell by an adhesive disposed between an interfacing portion of the resilient shell and a corresponding lip of the pocket which overlaps the interfacing portion of the resilient shell.

The LED light and sound ball for emergency responders is activated upon contact after being fired from a launcher to illuminate and direct responders to an area of interest, such as a potential crime scene. The ball includes a clear polymeric, spherical outer casing, and a rectangular, clear inner casing having a circuit board mounted therein. A plurality of rig rods extend through the inner casing and include curved heads that are in close proximity to the inner surface of the spherical outer casing. Upon impact, the outer casing flexes and pushes against one of the curved heads and pushes its associated rig rod inward, thereby closing a contact that triggers a control circuit to continuously illuminate a plurality of bright LEDs and continuously activate a sound generator that emits a foghorn-type alarm. The LED light and sound ball may be thrown or fired from a conventional compressed air launcher.

An apparatus having a control circuit including a computer processor and a computer memory configured with computer software. The control circuit causes a first test assembly to conduct an initial test of the air pressure within an inner chamber of a first tennis ball; and if the control circuit determines that the air pressure is below a threshold, a pressurization process increases the air pressure inside the inner chamber of the first tennis ball by piercing the outer skin of the first tennis ball with a needle, until a tip of the needle is in the inner chamber, and a first opening, plugged by the needle, is formed in the outer skin of the first tennis ball. The needle tip is thereafter withdrawn from the inner chamber of the first tennis ball, leaving the first opening unplugged and sealant is applied to the first opening to close the first opening.

According to one embodiment, an assembly ball includes a plurality of strips having a circumferential length. The strips are assembled convexly outward as viewed in the radial direction so as to substantially form a sphere as a whole. The strips each overlap other strips at their respective strip overlapping portions where the strips intersect with one another. The strip overlapping portions are joined by a strip joining member.

An object of the present disclosure is to provide a rubber composition containing an organic sulfur compound from which a molded product having a high hardness can be obtained. The present disclosure provides a rubber composition containing (a) a base rubber, (b) a co-crosslinking agent, (c) a crosslinking initiator, (d) a benzothiazole derivative, and (e) an organic sulfur compound, wherein (d) the benzothiazole derivative is a compound represented by the formula (1) and/or a compound represented by the formula (2).
