A room installation is provided having at least three walls, a ceiling and floor, all of which are covered in a mirrored surface. At least one transparent window allows ambient light into the room installation. A plurality of mirrored balloons are arranged within the room installation, and filled with helium, but otherwise weighted, to float substantially within a middle height of the room installation.

A balloon includes two joined plastic films. The balloon includes: a gas supply valve sandwiched between and joined to the first film and the second film; a first chamber receiving air supplied from the gas supply valve for expansion; and a second chamber communicating to the first chamber. The gas supply valve includes a gas passage that extends from a gas inlet positioned on an outer side of the second chamber to an inside of the first chamber through the second chamber. Part of the first film and the second film between the first chamber and the second chamber and between the gas passage and a peripheral edge of the balloon are joined together to form a first weld portion and a second weld portion. The first weld portion is formed on an opposite side of the second weld portion with the gas passage sandwiched therebetween.

A room installation including: a room having at least one wall, a ceiling, and a floor, each of which is at least partially covered by a mirrored surface; at least one transparent window to permit ambient light into the room; and a first plurality of mirrored balloons arranged within the room, and filled with a mixture of helium and another gas, the mixture configured to float the balloons of the first plurality of balloons substantially within a middle height of the room; and a plurality of vents to circulate and move the balloons of the first plurality of balloons in a designated pattern within the room.

A balloon valve and pouch assembly is mounted in a neck portion of a balloon and comprises a balloon valve and a pouch. The pouch is adapted to receive and retain an illumination device in a predetermined position. The valve has a valve inlet and a valve outlet provided at an opposite end of the valve. The valve is delimited by a sealing path and two layers. The pouch comprises an opening through which an illumination device can be inserted and, opposite the pouch opening, a closed end of the pouch. The pouch is delimited by a first sealing path and two additional layers. The two additional layers are heat-sealed together along the first sealing path, which is substantially V-shaped, with the open end of the V-shape defining the pouch opening and the closed end of the V-shape defining the closed end of the pouch.

A vent balloon for use over an air vent including an inflatable body operatively attached to a base on a proximal side, and a removable adhesive attached to a distal side of the base for attaching to an air vent. A method of using a vent balloon by removably adhering an inflatable body of the vent balloon through a base to an air vent, flowing air through the inflatable body, and inflating the inflatable body. A vent balloon for dispersing scent in a room, including an inflatable body operatively attached to a base on a proximal side, a removable adhesive attached to a distal side of the base for attaching to an air vent, and at least one scent mechanism operatively attached to the vent balloon for dispersing scent in the room. A method of dispersing scent in a room using the vent balloon.

A lighter-than-air holographic envelope such as a balloon decorated with a holographic pattern and having long float life (one week or longer) comprises a metal layer, an embossable layer, and a polymeric gas barrier of polyvinyl alcohol/polyvinyl amine copolymer crosslinked with citric acid and an optional additional crosslinking agent such as epichlorohydrin and a heat-seal layer.

A method for installing a universal air handler for a building air conditioning system includes installing a compact outdoor cabinet having a blower and separate intake and outlet chambers separated by an evaporator core. Cool and return air ducts from the building couple to each chamber. Return air drawn by the blower into the return air chamber passes across the evaporator, then through the blower and out through the cool air duct. Coolant lines couple the evaporator to a nearby stand-alone condenser/compressor unit. In one embodiment, an adapter enables stacking the condenser/compressor unit atop the cabinet to reduce the footprint of the combination. In another embodiment, a manifold couples permanently to the building air ducts and releasably couples to the cabinet. The universal air handler easily decouples from the manifold for transportation and maintenance. The manifold may be installed in various locations around the building, including on the roof.
