A liquid droplet-making composition is provided. The liquid droplet-making composition may provide a liquid droplet with improved retentivity by including cellulose ether and a saccharide.

A cost effective, structural building set, suitable as a toy, uses post connectors (10) comprised of a post (12) with attached disks (14), or similar devices that insert into cutouts (31) in geometric shaped component parts (30, 80, 180). More than one component part can be connected to the same post connector, and such component parts can rotate relative to the post axis. The connector design allows construction of stable structures of many sizes, shapes, and types, and readily facilitates hinging between different sections of such assembled structures.

A bubble producing device that includes a housing with a motor, a pump and an air producing device, all of which are electrically connected. A shaft with two ends, one end of which is connected to said housing and the second end is connectable to a bubble producing solution reservoir. A duct connected on one end to the air producing device and on the other end to a nozzle. The nozzle includes an open inner portion and an outer portion, wherein the outer portion includes a trough which surrounds an outer circumference of the nozzle and includes an outlet and an inlet. The inner portion includes a wiper secured therein. A solution channel pumps solution from the reservoir to the outlet to create bubbles and a recirculation channel pumps excess solution from the inlet back to the reservoir.

The present invention is a bubble, fog, haze, and fog-filled bubble machine. In particular, the present invention is directed to a single unit machine that can produce bubbles, fog, fog-filled bubbles or haze. The machine preferably comprises a housing having a front portal, a bubble section, a fog section, and a control interface, where the housing is connected to a power source. The bubble section is located behind the front portal and has a bubble wand motor attached to a rotatable wheel with a number of bubble wands. The bubble wands pass through a bubble fluid reservoir. The fog section is located behind the bubble section and comprises a fog outlet in front of a fan, where the fog outlet is connected to a fog heater core and a fog pump is in turn connected to a fog fluid reservoir. The control interface controls the selection of effects.

A device that creates micro or small-sized bubbles that resemble snow. The microbubble-producing device includes a shaft with a microbubble-producing solution reservoir connected to one end and a housing connected to a second end. The housing contains a motor, a pump, and an air-producing device, which are electrically connected to a power source. An air duct is connected on one end to the air-producing device and another end to a microbubble emitter. The emitter is hollow and includes an exterior wall. Secured to an inner surface of the wall is a shelf, which contains at least one orifice. A microbubble-producing solution input channel is a tubular structure with a first end submerged within the microbubble-producing solution reservoir and a second end connected to the shelf through the wall of the emitter.
