Abstract: A diving stick of the type which, after being tossed into a swimming pool, sinks to the bottom while maintaining an upright posture so that it can easily be grasped by a diver, includes a soft malleable outer body designed to prevent accidental impalement, and provisions for enabling the diving stick to sink and maintain an upright posture at the bottom of the pool despite the buoyancy of the soft malleable material.

Abstract: The present invention provides a versatile construction kit which can be used to easily form models of virtually any conceivable person, place or thing including a variety of vehicles, buildings, people, animals, weapons, machinery, caricatures, objects and the like. The construction kit comprises plural connectors which are connectable by a tongue-and-slot mechanism and optionally also by way of interconnectable notches by which they can be perpendicularly and detachably interconnected. The universal connectors are so versatile they can form virtually any geometric, regular, irregular, asymmetric, or symmetric configuration. They can be used to form a model of any known or imagined object. Generally, the width of the notches and of the slots of the connectors substantially approximates the thickness of the connectors.
