A variety of toy polariscopes are simpler in design and less costly than precision instruments used in scientific research and stress analysis of materials and structures. The toy polariscopes are designed for a variety of objects that may exhibit photoelastic properties such as glass, plastic, Plexiglas, gel candle material and other gels, and even edible photoelastic objects. They are specially designed for objects of various sizes with a variety of purposes such as objects to enhance learning in a variety of conditions and experiences. Special objects are designed to go with the toy polariscopes such as edible and inedible photoelastic objects, photoelastic candle material, a variety of photoelastic/photoplastic stands capable of a variety of displays in interaction with other designed photoelastic objects capable of a variety of interaction and displays. Other optical phenomena may also be observed.

Examples of a wave simulator for board sports and other uses are disclosed. An example wave simulator includes means for forming a wave, the means having at least one inclined side wall and a bottom corresponding to a desired wave shape. The wave simulator includes means for flowing water along at least partially along the inclined side wall and bottom of the flume to form a simulated wave. The wave simulator includes means for restraining a board rider in the means for forming a wave. Streamlines of the simulated wave are substantially parallel to a crest line of the simulated wave, and an inclined water flow ends in a downward arc.

A prompting device for prompting state information of a physical game character includes a smog machine and a control circuit. The smog machine include a smog chamber, a heating element, and an air-blowing device. The smog chamber has a receiving cavity for receiving smog fluid, an inlet, and an outlet. The inlet and the outlet are in communication with the receiving cavity. The heating element is mourned within the receiving cavity and generates heat to vaporize the smog fluid after an electric current is applied. The air-blowing device is disposed corresponding to the outlet for blowing art air flow towards the receiving cavity. The air flow generated by the air-blowing device enters into the receiving cavity from the inlet and discharges smog within the receiving cavity from outlet. The control circuit is configured to control the smog machine to generate the smog that characterizes the state information.

Described, is a gift box shaped container that opens to operate as a playset. The gift box shaped container includes a hack panel, two side panels, a front panel, a bottom panel, and a top panel serving as a lid. The lid is hingedly connected with the back panel and includes a decorative ribbon thereon. The front panel is hingedly connected with the bottom panel. Further, a latching mechanism connected with the lid and is operable for locking against the front panel. The latching mechanism includes a pull cord ribbon extending therefrom, with the pull cord ribbon connected with the latching mechanism such that pulling on the pull cord ribbon actuates the latching mechanism to cause the lid to detach from the front panel, thereby allowing a user to lift the lid and lower the front panel to convert the gift box shaped container into a playset.

In accordance with the present invention, a stand-alone pop up assembly and method for making the same is provided comprising a plurality of wall panels connected with an internal base. A roof structure is provided and a roof interface component for attaching the roof to the structure. The assembly is moveable between a first position being substantially flat into a one dimensional structure and a second position enfolded into a three dimensional structure by manipulating the outer structure and the internal base. The roof interface component may swivel into place during the movement to the three dimensional structure, thereby positioning the roof structure over the upper portions of the first and second panel walls or, alternatively, a sliding feature is provided with a tab from the roof inserted into a slot at the top of one of the panel walls, thereby sliding the roof into position.

A model toy includes: a main body portion; and a tray including a placement surface, the tray being stored inside the main body portion and configured to be drawn out from the main body portion. The main body portion includes a standing wall portion extending along a draw-out direction of the tray from an inner side of the main body portion to a position on or above the placement surface. The standing wall portion has a cutout portion that is cut out in an arc shape to face a draw-out side of the tray.

A toy for figure play includes: a shaft portion; a rotating body; and a suspension body. The rotation body includes: a bearing portion supported by the shaft portion so as to be rotatable in a circumferential direction of the rotating body around the shaft portion; a suspension portion; and a protrusion portion provided on an outer side than the suspension portion in a radial direction of the rotating body. The suspension body includes: a suspension connecting portion connected to the suspension portion to allow the suspension body to swing at least in the radial direction; a figure placement portion; and an abutting portion configured to be allowed to abut with the protrusion portion.
