Abstract: A rhythm spinner system includes a spinner assembly having an oblong body having a top surface, a bottom surface, and an inner volume housing a bearing assembly and a weighted member. The bearing assembly is located at a first-end of the spinner assembly and the weighted member is located and housed within a second-end of the spinner assembly opposing one another. The bearing assembly is configured to be gripped by a thumb and a finger of a user to be spun. The weighted member creates a pendulum-like swing that orbits an axis when a rhythmic motion is applied.

Abstract: The breathing system comprises a canister carrying layered filtering material, including activated carbon granules, a dessicant, a catalyst for the catalyzation of carbon monoxide to carbon dioxide, optionally lithium peroxide, for conversion of CO.sub.2 to O.sub.2, and electrostatically charged filters between the layers of filtering material. A mouthpiece carrying a noseclip, and inhalation and exhalation check valves and a whistle is disposed within a flexible, substantially completely transparent hear-through hood, both the mouthpiece and hood being disposed in the canister between the filtering material and a cover for the canister. In use, the cover is removed, air inlet apertures are uncovered, and the hood is drawn about an individual's head and substantially sealed about the neck. With the mouthpiece in the individual's mouth, and noseclip closing off the user's nose, inhalation causes air to flow through the filtering material and the inhalation check valve and past the exhalation check valves.
