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 Force founders of Liquid Force Tony Finn and Jimmy Redmon separately looked for alternatives to waterskiing and surfing. Tony Finn created the so-called „skurfer“ which had a similar shape to a surfboard but was much shorter. At the same time Jimmy Redmon came up with a water ski board which was produced by his own company Redline Designs. On contrary to the „skurfer“ the water ski board was a bit lighter and the first to have foot straps. Founding the World Wakeboard Association (WWA), a governing body for the sport, Redmon created several contests, where Finn worked as an announcer resulting
