An article is moveable between a first position and a second position and biased to the second position. The article is retained in the first position by retaining means until a predetermined condition is met and when met, the biasing means are released to move the article from the first position to the second position. The predetermined condition is met when at least one formation of a plurality of formations located with respect to at least one face of the article is moved from a first position to a second position, thereby releasing the retaining means. The article further includes user selection means to allow the user to select which one, or combination, of the plurality of formations, when moved, will cause the release of the retaining means.

An activity box includes two pairs of wheels having blind holes, two axles having two ends releasably insertable into the blind holes, and a box defining a space having a defined volume sufficiently large to fit the axles. The wheels include a first magnetically attractable component. The axles include a second magnetically attractable component secured at each end of each axle. The axles have a length spanning a width of the box, which has two pairs of through holes on two opposing sides to accommodate the axles, such that the axles are threaded through the through holes. The two pairs of wheels are rotatably attached to the box by magnetically coupling the first magnetically attractable component to the second magnetically attractable component, such that the activity box is configured to be used as a cart that can be rolled over a surface.

An amusement game station enables a user to operate complex machinery to pick up and position selectively shaped objects to promote complex machinery-based object placement skills. The amusement game station includes a complex machine component and at least one object-receiver station. The complex machine includes a user position station, a user-to-machine interface, a moveable member, and a pick-up mechanism. The moveable member is maneuvered relative to the user position station by way of manual operation of the user-to-machine interface. Each object-receiver station includes at least one object-receiving structure. The pick-up mechanism and moveable member are directable for picking up and conveying selectively shaped objects toward the object-receiving structure(s) for positioned placement. The amusement game station contemplates any number of shapes and sizes of the object-receiving stations and selectively shaped objects, including basically shaped objects and stations as well as irregularly shaped objects and stations.

Apparatus and methods are disclosed for sealing openings on containers and other structures, permitting selective removal of portions of the seal structure, and for similar selective removal of portions of adhesive elements such as bandages.

A puzzle kit and a puzzle constructed from said puzzle kit. The puzzle kit comprises a three dimensional substrate having an outer surface, and a plurality of puzzle pieces that cannot interlock. Each puzzle piece has a first surface and an opposite second surface and a thickness defined between the first and second surfaces. Each puzzle piece comprises first attachment means and the outer surface of the substrate defines a plurality of complementary second attachment means, such that the first attachment means and the second attachment means magnetically attach each puzzle piece to the outer surface. The first attachment means comprises a projection extending from the second surface of the puzzle piece. The second attachment means comprises a hole to partly receive the projection.
