There is described a wind powered device including a vertical support, a horizontal support rotatably attached to the vertical support, and planar elements respectively attached to opposite ends of the horizontal support by articulating hinge elements. The articulating hinge elements are connected to ones of the planar elements at respective positions that are horizontally offset from the center of each planar element, and each hinge element can rotate through a predetermined maximum throw angle.

A drinking container has a spinner mechanism that includes a spinner housing for providing a spinner chamber. A spinner disk fits securely within the spinner chamber when rotatably mounted therein. The spinner mechanism includes a fluid input through the chamber perimeter surface, and a fluid outlet for allowing the liquid out of the spinner chamber once it has contacted the spinner disk. A jet nozzle directs a liquid from the fluid input across top and bottom surfaces of the spinner disk. The spinner disk does not include paddles, but relies primarily on viscous and adhesive forces to transfer energy from the flowing liquid to the surface of the spinner disk.

A blowout in which the required exhaling force of for stretching thereof may be precisely set to a suitable level. The blowout may include: a stretchable body having a generally tubular shape; a wire body having elasticity and arranged along the longitudinal direction of the stretchable body; and a mouthpiece connected to an end of the stretchable body. In use, the mouthpiece may be held in the mouth such that air is blown therethrough, whereby the stretchable body is stretched. The stretchable body remains curled into a spiral shape by the wire body when air is not blown thereinto. The elastic force of the wire body may be set to a predetermined value, the mouthpiece may include an air regulator for regulating the quantity of airflow, and the stretchable body may not stretch unless the force of air blown is equal to or more than a predetermined value.

A system and method for actuating controlled stimulation of a patient in a confined medical position helps sooth and entertain a patient receiving medical treatment while resting on a support member, like a dental chair. The system provides a support member, and integrates at least one air actuated animated member, such as a mobile or figurine, proximal to the support member, to enable animated motion by the animated member through pressurized air. Pressurized air causes the animated members to articulate in animated, colorful movements. Audio signals are also generated by the animated member in response to the pressurized air. The animated member can be a mobile or a cartoon character with joints, axes, and limbs that move when engaged by pressurized air. The patient or caregiver control distribution of the pressurized air by manipulating a foot valve and an arm valve to control the animated members.

An action toy employs a vacuum chamber and vacuum pressure to propel projectiles inward to collide with materials or objects or structures inside the sealed vacuum chamber. Users are entertained by observing high-speed demolition and wrecking action. Air-tight containment of the chamber is required to create a vacuum, ensuring user safety and mess-free operation while providing close-up viewing and video capture from outside the chamber. Users can experiment with a wide variety of high-speed collisions, watch the results in slow-motion replay, and share replay clips with others using a smartphone. The toy can be used to create art works by blasting materials onto a canvas.
