Liquid metal imbalance of the surface tension induces a pressure difference between the rear and the head, which produces a thrust to drive the droplet toward the head; at the same time, the hydrogen produced in the electrochemical reaction process also further raises the thrust. The discovery of this phenomenon laid the technical foundation for the development of intelligent motors, vascular robots, fluid pumping systems, flexible actuators and even more complex liquid metal robots. Liquid metal Liquid metal consists of alloys with very low melting points which form a eutectic that is liquid at room temperature. The standard metal used to be
Liquid latex mixed with the liquid latex solution for custom colors but may not be suitable for use a cosmetic application. Liquid latex used for special effect make-up projects like scars and gashes incorporate flesh colored latex that is applied to the skin and then built up using materials such as tissue paper and cotton. "Liquid latex safety guidelines" Liquid latex Liquid latex is often used for special effects make-up and body painting applications. Liquid latex contains about one-third latex, two-thirds water (plus less than one percent ammonia to keep the latex from spoiling and to control the pH of the solution).
