Moolooite is a rare blue-green mineral, a hydrated copper oxalate with an orthorhombic crystalline structure. It is a mineral with the formula Cu++(C2O4)·n(H2O) (n<1) (copper…

Acoustic levitation uses acoustic radiation forces to counteract gravity and suspend objects in mid-air. It is a method for suspending matter in the air against…

Limestone is a sedimentary rock type of carbonate; it is predominantly composed of calcium carbonate (CaCO3), typically in the form of calcite or aragonite. It…

In aerodynamic levitation, solids and liquids are floated in a vertical gas stream. Aerodynamic levitation is the use of gas pressure to levitate materials so…

A clinostat is an apparatus for studying tropisms in plants, usually a rotating disc to which the plant is attached so that it receives an…

Magnetic levitation is the suspension of an object above or below a second object by means of magnetic repulsion or attraction. It is also known…

A coral island is a type of island made of coral detritus and organic matter associated with it. Coral islands are lowland, maybe just a…

Optical tweezers are tools based on strongly focused light, enable optical trapping, manipulation, and characterization of a wide range of microscopic and nanoscopic materials. They…

A tractor beam is a device with the ability to attract one object to another from a distance. In science fiction, it is a hypothetical…

Anti-gravity is the antithesis of gravity; a hypothetical force by which a body of positive mass would repel a body of negative mass. It also…
