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
