Bubbleator
The Bubbleator was a large, bubble-shaped hydraulic elevator with transparent acrylic glass walls operated from an elevated chair built for the 1962 World's Fair in Seattle. These transparent walls gave the illusion of looking through an actual 'soap bubble' by refracting light to obtain a rainbow-like effect for the riders inside. It was originally part of the Washington State Coliseum (now a sports venue known as Climate Pledge Arena), where it lifted 100 passengers at a time up one floor through a structure of interlocking aluminum cubes to the "World of Tomorrow" exhibit. T. C. Howard of Synergetics, Inc. designed the Bubbleator and the exhibit. After the fair, the Bubbleator was relocated to the Center House at Seattle Center. By 1984, it had been removed and put in storage to make way for the Seattle Children's Museum. It was sold to a private owner in Des Moines, Washington, who recycled the upper part of the dome into a greenhouse. The control chair, which had also been in ...

Elevator
An elevator or lift is a wire rope, cable-assisted, hydraulic cylinder-assisted, or roller-track assisted machine that vertically transports people or freight between floors, levels, or deck (building), decks of a building, watercraft, vessel, or other structure. They are typically powered by electric motors that drive traction cables and counterweight systems such as a hoist (device), hoist, although some pump hydraulic fluid to raise a cylindrical piston like a hydraulic jack, jack. In agriculture and manufacturing, an elevator is any type of conveyor device used to lift materials in a continuous stream into bins or silos. Several types exist, such as the chain and bucket elevator, grain auger screw conveyor using the principle of Archimedes' screw, or the chain and paddles or forks of hay elevators. Languages other than English, such as Japanese, may refer to elevators by loanwords based on either ''elevator'' or ''lift''. Due to wheelchair access laws, elevators are ...

Acrylic Glass
Poly(methyl methacrylate) (PMMA) belongs to a group of materials called engineering plastics. It is a transparent thermoplastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Plexiglas, Acrylite, Astariglas, Lucite, Perclax, and Perspex, among several others ( see below). This plastic is often used in sheet form as a lightweight or shatter-resistant alternative to glass. It can also be used as a casting resin, in inks and coatings, and for many other purposes. Although not a type of familiar silica-based glass, the substance, like many thermoplastics, is often technically classified as a type of glass, in that it is a non-crystalline vitreous substance—hence its occasional historic designation as ''acrylic glass''. Chemically, it is the synthetic polymer of methyl methacrylate. It was developed in 1928 in several different laboratories by many chemists, such as William Chalmers, Otto Röhm, and Walter Bauer, and first brought ...

Climate Pledge Arena
Climate Pledge Arena is a multi-purpose indoor arena in Seattle, Washington, United States. It is located north of Downtown Seattle in the entertainment complex known as Seattle Center, the site of the 1962 World's Fair, for which it was originally developed. After opening in 1962, it was subsequently bought and converted by the city of Seattle for entertainment purposes. From 2018 to 2021, the arena underwent a $1.15 billion redevelopment; the renovation preserved the original exterior and roof, which was declared a Seattle Landmark in 2017 and was listed on the Washington Heritage Register as well as the National Register of Historic Places in 2018.

Aluminum
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity towards ox ...

Greenhouse
A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of Transparent ceramics, transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external temperature, protecting its contents in cold weather. Many commercial glass greenhouses or hothouses are high tech production facilities for vegetables, flowers or fruits. The glass greenhouses are filled with equipment including screening installations, heating, cooling, and lighting, and may be controlled by a computer to optimize conditions for plant growth. Different techniques are then used to manage growing conditions, including air temperature, relative humidity and vapour-pressure deficit, in ord ...
