The Betz mystery sphere is a metal sphere with an approximate diameter of 8 inches (20 cm) weighing nearly 22 pounds (10 kg) uncovered in 1974 by a family in Florida. [ 1 ] [ a ] Background
The Magdeburg hemispheres are a pair of large copper hemispheres with mating rims that were used in a famous 1654 experiment to demonstrate the power of atmospheric pressure. When the rims were sealed with grease and the air was pumped out, the sphere contained a vacuum and could not be pulled apart by teams of horses. Once the valve was opened ...
A dome is a self-supporting structural element of architecture that resembles the hollow upper half of a sphere. Every dome in the world which was the largest-diameter dome of its time is listed. Notes: Each structure is only described in detail once (the appearance closest to the top of the page), even if it appears on multiple lists.

An example of a spherical cap in blue (and another in red) In geometry, a spherical cap or spherical dome is a portion of a sphere or of a ball cut off by a plane.It is also a spherical segment of one base, i.e., bounded by a single plane.
The pits of the first nuclear weapons were solid, with an urchin neutron initiator in their center. The Gadget and Fat Man used pits made of 6.2 kg of solid hot pressed plutonium-gallium alloy (at 400 °C and 200 MPa in steel dies – 750 °F and 29,000 psi) half-spheres of 9.2 cm (3.6 in) diameter, with a 2.5 cm (1 in) internal cavity for the initiator.
The Unisphere measures 140 feet (43 m) high and 120 feet (37 m) in diameter. It sits atop a 20-foot-tall (6.1 m) tripod base with over 500 steel pieces representing the countries, as well as three steel rings representing the first artificial satellites orbiting Earth. Around the Unisphere is a reflecting pool measuring 310 feet (94 m) in ...
A Horton sphere (sometimes spelled Hortonsphere), also referred to as a spherical tank or simply sphere, is a spherical pressure vessel, which is used for industrial-scale storage of liquefied gases. Example of materials that can be stored in Horton spheres are liquefied petroleum gas (LPG), liquefied natural gas (LNG), and anhydrous ammonia .
