Abstract

We describe the inspiration, development, and deployment of a novel cocktail device modeled after a class of water-walking insects. Semi-aquatic insects like Microvelia and Velia evade predators by releasing a surfactant that quickly propels them across the water. We exploit an analogous propulsion mechanism in the design of an edible cocktail boat. We discuss how gradients in surface tension lead to motion across the water's surface, and detail the design considerations associated with the insect-inspired cocktail boat.

摘要

我们描述了一种仿照一类水上行走昆虫设计的新型鸡尾酒装置的灵感来源、开发过程及应用情况。像细足猎蝽和毛蝽这样的半水生昆虫通过释放一种表面活性剂来躲避捕食者，这种表面活性剂能迅速推动它们在水面上滑行。我们在可食用鸡尾酒船的设计中运用了类似的推进机制。我们探讨了表面张力梯度如何导致物体在水面上移动，并详细介绍了与受昆虫启发的鸡尾酒船相关的设计考量。
