Abstract: A collapsible toy air gun with at least two tapered tubular sections adapted to be cooperatively joined coaxially, at least one supporting plate, a diaphragm and a resilient string. The tapered tubular sections are correspondingly sized concentrically to form a tubular body having a larger and an opposite smaller opening end in the extended operational position. At least one supporting plate is mounted on the circumferential surface of the tubular body to maintain the tubular sections in the extended position. The diaphragm is mounted transversely across the larger opening end of the tubular body with a pull knob and back support secured to the diaphragm. The resilient string is mounted across the smaller opening end of the tubular body through the back support.

Abstract: A portable, self-contained, black light device that is incorporated into or adaptable to a head gear to be used in combination with fluorescent or phosphorescent material for entertaining effect or promotional purposes. The portable black light device has a housing with a plurality of openings, a plurality of UV LEDs protruding from each opening and a power source within the housing for energizing the UV LEDs. With the portable black light device incorporated or adaptable to the visor or brim of a head gear, and in combination with fluorescent paint or make up on a wearer's face or fluorescent decorative element, cause the fluorescent paint to glow as if internally lit, providing an effective entertainment or advertisement.

Abstract: An electronic musical device having a keyboard actuated by random liquid drops. The device includes a base, a synthesizer, a keyboard having a plurality of keys pivotably attached to the base to actuate the synthesizer and a tube assembly extending above the keys that produces drops of liquid that fall periodically onto the keys to produce a melody.
