A toy having three bobs on a string where the middle bob slides. A low moment of inertia of the middle bob is desirable because it minimizes tangling of the string about the middle bob and produces smooth, tactile-appealing orbits. Each bob has a pair of mated throughbore pieces sandwiching a central metal weight and an equatorial bag stuffed with low-density pellets. Concave sections (in profile on a plane along the polar axis) of the throughbore occupy a substantial portion of the length of the throughbore to take best advantage of the torques produced by the string by focusing the tension of the string at the mouths of the throughbore. The concave sections also reduce the volume occupied by the bag, thereby reducing moment of inertia. Additionally, hollows in the concave regions of the throughbore pieces further reduce the moment of inertia.

A game machine makes it possible to make an accurate determination of not only success but also failure with regard to a predetermined play action, and can handle various play rules. The game machine includes at least one game machine main body, and at least one game machine sub unit configured to enable a play by being arranged in a predetermined position on the game machine main body, and is characterized in that, to provide an evaluation of successful play when the game machine sub unit is positioned in the predetermined position on the game machine main body, the game machine main unit and/or the game machine sub unit is provided with a position grasping unit for grasping a positional relationship of the main body and the sub unit. The position grasping unit includes a sensing device utilizing an electric change.

A mixed reality golf simulation and training system that can use, along with a user's existing standard golf equipment, a golf ball launch monitor to track the initial ball positional data, spin and acceleration, and simulate the complete ball path and location or use complete ball tracking data and displays the actual ball path and location. Mixed reality glasses allow the display of ball tracking data over the real world view and/or an immersive display of a simulated world view, depending on the user's head or view position. Golf simulation graphical views can include various options, including simulated or panoramic photographic views of a golf course, simulated graphics and data superimposed over a real world driving range view, or simple ball tracking data superimposed over a real world view at any location.

A piata hanging or holder device offers the user stability and flexibility in controlling a piata at party events. The hanging device is collapsible for shipping and storage. The hanging device is easily assembled and utilizes the user's weight to further stabilize the device from falling or tilting. For assembly, guiding marks are providing in poles to assist the user for ease of assembly. One benefit of this device is that the device does not require anchoring or include a ballast to keep the handing device erect, which reduces shipping and manufacturing cost.

An object toss game has a ball connected to an elastic cord. The ball has a surface with fasteners. Two board assemblies are positioned at a distance apart. Pads are arranged on a top panel of each board assembly. Players toss the ball toward a pad on the board to remove the pad from the top panel. The ball then bounces from the top panel to remove the pad from the top panel. The first player to remove the pads from a board positioned opposite to the player wins the game. Alternately, players take turns tossing darts at regions on the board assemblies that are assigned points.
