Surface tension biomimetics need to have a transplant or repair performed. Microvelia exploit surface tension by creating a surface tension gradient that propels them forward by releasing a surfactant behind them through a tongue-like protrusion. Biomimetic engineering was used in a creative and fun way to make and edible cocktail boat that mimicked the ability of microvelia to propel themselves on the surface of water by means of a phenomenon called the marangoni effect. Burton and her colleagues used 3D printing to make small plastic boats that released different types of alcohol behind the boat to lower the surface tension and create a
Surface tension of the film increases by (the factor of 2 is here because the liquid has two sides, two surfaces). Thus, multiplying both the numerator and the denominator of by , we get This work is, by the usual arguments, interpreted as being stored as potential energy. Consequently, surface tension can be also measured in SI system as joules per square meter and in the cgs system as ergs per cm. Since mechanical systems try to find a state of minimum potential energy, a free droplet of liquid naturally assumes a spherical shape, which has the minimum surface area for a
