The Water Clock, also known as The Giant Water Clock, is in the permanent collection of The Children's Museum of Indianapolis located in Indianapolis, Indiana, United States. The modern water clock is located in the Sunburst Atrium of The Children's Museum, and is adjacent to the Grand Staircase leading up to the second floor. It was created by French scientist and artist Bernard Gitton in 1988, the same year that the museum acquired it. The artistic timepiece is the largest water clock in North America. Description The water clock, created by French chemist and artist Bernard Gitton, is approximately tall and made of more than 40 pieces of glass and 100 pieces of metal. The lights on the clock are bright green and the water is dyed blue. The clock is made of glass, steel, and of a solution of deionized water, methyl alcohol, and coloring dye. It was assembled in France to ensure that it worked, then disassembled and shipped to Indianapolis. It was assembled again in the Chi ...

The Children's Museum Of Indianapolis
The Children's Museum of Indianapolis is the world's largest children's museum. It is located at 3000 North Meridian Street, Indianapolis, Indiana in the United Northwest Area neighborhood of the city. The museum is accredited by the American Alliance of Museums. It is with five floors of exhibit halls and receives more than one million visitors annually. Its collection of over 130,000 artifacts and exhibit items is divided into two domains: Arts & Humanities and the Natural Sciences. Among the exhibits are a simulated Cretaceous and Jurassic dinosaur habitats, a carousel, a steam locomotive, and the glass sculpture ''Fireworks of Glass Tower and Ceiling''. The museum's focus is family learning; most exhibits are designed to be interactive, allowing children and families to actively participate. Founded in 1925 by Mary Stewart Carey with the help of Indianapolis civic leaders and organizations, it is the fourth-oldest such institution in the world. The current site became home f ...

Deionized Water
Purified water is water that has been mechanically filtered or processed to remove impurities and make it suitable for use. Distilled water was, formerly, the most common form of purified water, but, in recent years, water is more frequently purified by other processes including capacitive deionization, reverse osmosis, carbon filtering, microfiltration, ultrafiltration, ultraviolet oxidation, or electrodeionization. Combinations of a number of these processes have come into use to produce ultrapure water of such high purity that its trace contaminants are measured in parts per billion (ppb) or parts per trillion (ppt). Purified water has many uses, largely in the production of medications, in science and engineering laboratories and industries, and is produced in a range of purities. It is also used in the commercial beverage industry as the primary ingredient of any given trademarked bottling formula, in order to maintain product consistency. It can be produced on-site for imme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methyl Alcohol
Methanol (also called methyl alcohol and wood spirit, amongst other names) is an organic chemical and the simplest aliphatic alcohol, with the formula C H3 O H (a methyl group linked to a hydroxyl group, often abbreviated as MeOH). It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol (potable alcohol). A polar solvent, methanol acquired the name wood alcohol because it was once produced chiefly by the destructive distillation of wood. Today, methanol is mainly produced industrially by hydrogenation of carbon monoxide. Methanol consists of a methyl group linked to a polar hydroxyl group. With more than 20 million tons produced annually, it is used as a precursor to other commodity chemicals, including formaldehyde, acetic acid, methyl tert-butyl ether, methyl benzoate, anisole, peroxyacids, as well as a host of more specialised chemicals. Occurrence Small amounts of methanol are present in normal, healthy human ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Water Clock
A water clock or clepsydra (; ; ) is a timepiece by which time is measured by the regulated flow of liquid into (inflow type) or out from (outflow type) a vessel, and where the amount is then measured. Water clocks are one of the oldest time-measuring instruments. The bowl-shaped outflow is the simplest form of a water clock and is known to have existed in Babylon, Egypt, and Persia around the 16th century BC. Other regions of the world, including India and China, also have early evidence of water clocks, but the earliest dates are less certain. Some authors, however, claim that water clocks appeared in China as early as 4000 BC. Water clocks were also used in ancient Greece and ancient Rome, described by technical writers such as Ctesibius and Vitruvius. Designs A water clock uses the flow of water to measure time. If viscosity is neglected, the physical principle required to study such clocks is Torricelli's law. There are two types of water clocks: inflow and outflo ...

Bernard Gitton
Bernard Gitton (); born 24 June 1935) is a French physicist and artist who has built modern water clocks, fountains and other devices relating art and science. Biography He constructed " The Water Clock", at The Children's Museum of Indianapolis, "Clepsydra Water Clock" at Abbotsford, British Columbia, " Time Flow Clock" Europa Center, Berlin, and "Time-Flow Clock" Rødovre Centrum, Denmark. Also, he projected the Water Clocks displayed at the Iguatemi Mall in São Paulo city and the Iguatemi Mall in Porto Alegre, Brazil. The clock stands there since 1983. One of his clocks was installed in the 1990s at Yabachō Station is an underground metro station located in Naka-ku, Nagoya, Aichi Prefecture, Japan, operated by the Nagoya Municipal Subway. It is located 2.3 rail kilometers from the terminus of the Meijō Line at Kanayama Station. This station provides a ... in Nagoya, Japan.

Siphon
A siphon (from grc, σίφων, síphōn, "pipe, tube", also spelled nonetymologically syphon) is any of a wide variety of devices that involve the flow of liquids through tubes. In a narrower sense, the word refers particularly to a tube in an inverted "U" shape, which causes a liquid to flow upward, above the surface of a reservoir, with no pump, but powered by the fall of the liquid as it flows down the tube under the pull of gravity, then discharging at a level lower than the surface of the reservoir from which it came. There are two leading theories about how siphons cause liquid to flow uphill, against gravity, without being pumped, and powered only by gravity. The traditional theory for centuries was that gravity pulling the liquid down on the exit side of the siphon resulted in reduced pressure at the top of the siphon. Then atmospheric pressure was able to push the liquid from the upper reservoir, up into the reduced pressure at the top of the siphon, like in a baromet ...

Hornsby Water Clock
The Hornsby Water Clock, titled ''Man, Time and the Environment'' is a piece of kinetic art, kinetic sculpture, a decorative fountain and a functional clock in the Florence Street pedestrian mall in Hornsby, New South Wales, Hornsby, New South Wales, Australia. Unveiled in 1993, the sculpture was designed and engineered by Victor Cusack and constructed of bronze, stainless steel and glass by Victor and his foundry floor manager Rex Feakes. Construction, including alterations to the mall, cost over Australian dollar, A$1 million and took two and half years; thereafter, chicken bones and other carelessly discarded items caused many breakdowns before the water filtration system was upgraded. Overview Thought by some to have actually been at Hornsby much longer than when it was unveiled in 1993, it is a combination of three Water clock, water-powered clocks – a 4th-century BC Greece, Greek clepsydra, an 11th-century China, Chinese water wheel clock and a 17th-century Switzer ...
