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 in a phenomenon known as capillary action. The height to which the column is lifted is given by Jurin's law: where Pouring mercury onto a horizontal flat sheet of glass results in a puddle that has a perceptible thickness. The puddle will spread out only to the point where it is a little under half a centimetre thick, and no thinner. Again this is due to the action of mercury's strong surface tension. The liquid mass flattens out because that brings as much of the mercury to as low a level as possible, but the surface tension, at the same
