Marangoni effect

就今天看paper看到的，還滿屌的一個現象
http://en.wikipedia.org/wiki/Marangoni_effect
"Since a liquid with a high surface tension pulls more strongly on the surrounding liquid than one with a low surface tension, the presence of a gradient in surface tension will naturally cause the liquid to flow away from regions of low surface tension. The surface tension gradient can be caused by concentration gradient or by a temperature gradient (surface tension is a function of temperature)."

NASA也有做相關的研究

以後我應該也會用到

P.S. 好無聊的文章，都沒有個人意見 Orz
