Venomous Agent X, aka VX ( IUPAC name O-ethyl S-[2-(diisopropylamino)ethyl] methylphosphonothioate) is an extremely toxic substance that has no known uses except in chemical warfare as a nerve agent. It is a tasteless and odorless liquid with an amber-like color. 10 milligrams is sufficient for it to be fatal through skin contact and the LCt for inhalation is estimated to be 30–50 mg·min/m. As a chemical weapon, it is classified as a weapon of mass destruction by the United Nations in UN Resolution 687. The production and stockpiling of VX exceeding 100 grams per year was outlawed by the Chemical Weapons Convention of 1993.
The VX nerve agent is the best-known of the V-series of nerve agents and is considered an area denial weapon due to its physical properties. It is far more powerful than sarin, another well known nerve agent toxin, but works in a similar way.

VX was a short-lived and unsuccessful consumer analog recording videocassette format developed by Matsushita and launched in 1975 in Japan. In the US it was sold using the Quasar brand and marketed under the name "The Great Time Machine" to exhibit its time-shifting capabilities, since VX machines had a companion electro-mechanical clock timer for timed recording of television programs. In Japan, the VX-100 model was launched in 1975, with the VX-2000 following in 1976. The first and only model sold in North America was the Quasar VR-1000 (based on the Panasonic VX-2000), with the VT-100 timer.
VX, originally ' Rock-It-Ball', is a ball sport from the UK. It evolved in North Yorkshire ( Great Britain) and was launched in February 2006 at the Youth Sport Trust's Sports Colleges Conference. The sport was continually developed by the International Federation and in 2012 the Federation approved a move by the worldwide membership to rename the sport VX to cater for its international development.
VX has continued to be popular in schools in the UK and is now being adopted by universities, colleges, youth organisations, Street Games and the military. It is also attracting interest from the Prison Service and Primary Care Trusts. It now has a foothold in 25 countries of which 15 have National Governing Bodies(NGBs).
VX is a totally gender-neutral sport. Males and females play on a totally equal footing in all disciplines and at all levels. It is also accessible to players of all abilities. It is not an adaptation of any single sport however there are elements of several sports including dodgeball, lacrosse, basque pelota and hockey.
