Sphere floating on a very thin film of water on a fountain basin
This article is about the sculpted fountains. For other uses, see Kugel (disambiguation).
Principle of operation of a Kugel fountain (A) Water flowing between the sphere and its shaped holder lifts the ball slightly. (B) Water flows over the sides into a reservoir. (C) Water is pumped back in an endless loop. (D) Pump. (E) Ball can easily be moved by hand.
A kugel fountain (also called a floating sphere fountain or by the pleonasmic name kugel ball) is a water feature or sculpture where a sphere sits in a fitted hollow in a pedestal, and is supported by aquaplaning on a thin film of water. Pressurized water flows between the sphere and socket, creating a mechanical hydrostatic bearing that is nearly frictionless. The sphere can weigh thousands of kilograms, but the efficient bearing allows it to be spun by the force of a hand. The sphere does not float, being denser than water; it is often made from granite.[1] The hydraulics of the fountain can be controlled so that the axis of rotation of the sphere changes continually.[2] Ring sculptures that rotate on an axis are also built.[2][3]
Kugel fountains can be found all over the world. Many are at popular tourist destinations, such as science museums,[4] shopping centers, lobbies, and gardens.
Located at McKnight Park. Kugel ball is a representative of a baseball, and bears the signature of Boston Red Sox pitcher and Murfreesboro native David Price. Miracle Field was constructed with funds from Price's charity, Project One Four. The facility opened on 6 May 2017.[20]
Lansdale is a borough in Montgomery County, Pennsylvania, United States. It is a densely-populated commuter town, with many residents traveling daily to Philadelphia using SEPTA Regional Rail's Lansdale/Doylestown Line. In 1900, 2,754 people lived here; in 1910, 3,551; and in 1940, 9,316 people were inhabitants of Lansdale. The population was 18,773 at the 2020 census.
The macroscopic scale is the length scale on which objects or phenomena are large enough to be visible with the naked eye, without magnifying optical instruments. It is the opposite of microscopic.
The Mpemba effect is the name given to the observation that a liquid which is initially hot can freeze faster than the same liquid which begins cold, under otherwise similar conditions. There is disagreement about its theoretical basis and the parameters required to produce the effect.
The hairy ball theorem of algebraic topology (sometimes called the hedgehog theorem in Europe) states that there is no nonvanishing continuous tangent vector field on even-dimensional n-spheres. For the ordinary sphere, or 2‑sphere, if f is a continuous function that assigns a vector in R3 to every point p on a sphere such that f(p) is always tangent to the sphere at p, then there is at least one pole, a point where the field vanishes (a p such that f(p) = 0).
Aquaplaning or hydroplaning by the tires of a road vehicle, aircraft or other wheeled vehicle occurs when a layer of water builds between the wheels of the vehicle and the road surface, leading to a loss of traction that prevents the vehicle from responding to control inputs. If it occurs to all wheels simultaneously, the vehicle becomes, in effect, an uncontrolled sled. Aquaplaning is a different phenomenon from when water on the surface of the roadway merely acts as a lubricant. Traction is diminished on wet pavement even when aquaplaning is not occurring.
Kugel is a baked casserole, most commonly made from lokshen or potato. It is a traditional Ashkenazi Jewish dish, often served on Shabbos and Jewish holidays. American Jews also serve it for Thanksgiving dinner.
The Sphere is a monumental cast bronze sculpture by German artist Fritz Koenig (1924–2017).
The Science Museum of Virginia is a science museum located in Richmond, Virginia. Established in 1970, it is an agency of the Commonwealth of Virginia. It is housed in the former Broad Street Station, built in 1917.

A yard globe is a mirrored sphere displayed as a lawn ornament, typically atop a conical ceramic or wrought iron stand. Sizes ranges from 1 in (25 mm) up to 10 m (33 ft) in diameter, with the most popular gazing ball being 12 in (300 mm). Gazing balls were originally made of glass, but may now be made of stainless steel, acrylic, ceramic, or stained glass.
The Stover Canal is a canal located in Devon, England. It was opened in 1792 and served the ball clay industry until it closed in the early 1940s. Today it is derelict, but the Stover Canal Society is aiming to restore it and reopen it to navigation.
Waboba is an international outdoor toy and sporting goods brand headquartered in Stockholm, Sweden with offices in Atlanta, Georgia and Guangzhou, China. Waboba is most known for its invention of balls that bounce on water, the high bouncing Moon ball, and the Wingman silicone flying disc. The company specializes in beach and backyard toys and games. The slogan used in advertising is Keep Life Fun. The name Waboba is a registered trademark and many of its products are internationally patented.
The Somerset Space Walk is a sculpture trail model of the Solar System, located in Somerset, England. The model uses the towpath of the 22-kilometre (14-mile) Bridgwater and Taunton Canal to display a model of the Sun and its planets in their proportionally correct sizes and distances apart. Unusually for a Solar System model, there are two sets of planets, so that the diameter of the orbits is represented.
Bottle flipping was a trend that involved throwing a plastic bottle, typically partially whole of liquid, into the air so that it rotates in an attempt to land it upright on its base or cap. It became an international trend in the summer of 2016, with numerous videos of people attempting the activity being posted online. With its popularity, the repetitive thuds of multiple attempts have been criticized as a distraction and a public nuisance. Parents and teachers have expressed frustration at the practice, resulting in water bottle flipping being banned at several schools worldwide and many people calling for the practice only to be performed in private.
The physics of a bouncing ball concerns the physical behaviour of bouncing balls, particularly its motion before, during, and after impact against the surface of another body. Several aspects of a bouncing ball's behaviour serve as an introduction to mechanics in high school or undergraduate level physics courses. However, the exact modelling of the behaviour is complex and of interest in sports engineering.
