Isolation (illusion) important developments was the combination of crystal ball isolations and body-popping/locking/waving dance styles, as seen in the styles of, amongst others, Nik Robson and Matt Hennem in the '90s. Isolation (illusion) In contact juggling, poi spinning, hooping and other types of object manipulation, an isolation is an illusion whereby a prop appears to float in space, with the performer's hands and body moving around it. In reality the performer is supporting the prop, and countering his or her movement relative to the prop. Michael Moschen is originally credited for developing several of the techniques for ball isolations (as well as
Matrix isolation (ether/isopentane/ethanol 5:5:2). The modern matrix isolation technique was developed extensively during the 1950s, in particular by George C. Pimentel. He initially used higher-boiling inert gases like xenon and nitrogen as the host material, and is often said to be the "father of matrix isolation". Matrix isolation Matrix isolation is an experimental technique used in chemistry and physics which generally involves a material being trapped within an unreactive matrix. A "host" matrix is a continuous solid phase in which "guest" particles (atoms, molecules, ions, etc.) are embedded. The guest is said to be "isolated" within the host matrix. Initially the term
