A delivery system and method for levitation is disclosed. The delivery system includes an inlet trough; a queue aligned with the inlet trough; a blocker conduit aligned with the queue; a first blocker and a second blocker, each having an extension through the blocker conduit for selectively permitting passage through the blocker conduit, the extension of the first blocker spaced laterally along the blocker conduit from the extension of the second blocker; an exhaust conduit having an exhaust conduit receiver opening and an exhaust conduit exit opening, the exhaust conduit receiver opening aligned with a blocker conduit exit opening of the blocker conduit; and a force generator positioned near the base end and below the exhaust conduit receiver opening. A rolling object can exit through the exhaust conduit exit opening and levitate above the exhaust conduit exit opening. The delivery system can include a speed reducer.

A toy that is comprised of diverse cylindrical tubes, channels, and spouts to provide entertainment and educational value for the user through engineering a route for the transfer of water and other objects. These tubes are positioned in manners of various directions and secured to a surface, likely a shower wall or bath tub, with rubber suction cups or other affixing mechanism, which are easily repositioned and moved by the user. The issue addressed with this invention is as follows: children become easily bored and unengaged in the shower or bath, and this toy would provide for not only entertainment, but engineering experience for the child, as they would be constructing an effective path for the water.

A scoring device and methods of scoring a snowball fight. The device worn by a person has a target portion and a scoring chamber portion. The target portion includes a target, and the scoring chamber portion is coupled below the target portion and is arranged to accumulate and store snow falling from the target portion. In some embodiments the target portion also includes a permeable layer coupled to the target in a spaced apart construction to form an interior region between the permeable layer and the target, the permeable layer configured to allow snow from snowballs to pass through the permeable layer and into the interior region before falling into the scoring chamber portion. In some embodiments a stopper element at least partially separates the target portion from the scoring chamber portion, to limit the amount of snow that exits the scoring chamber portion when the person bends over.

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.
