We are all familiar with tides, and how the moon generates these. I’ve long been intrigued by the thought that all water feels and succumbs to the pull of the moon, This otherwise capricious compound, compelled into movement by a celestial body some 384,400 kilometres distant. And so I decided to determine whether I could detect the influence of the moon on a minute drop of salt water using a powerful DIC microscope. It seems that tides are present even in the most minute drop of this fluid, and that these leave behind microscopic tidelines. How wonderful is it, that a tiny drop of water and the moon are connected over hundreds of thousands of kilometres of empty space and that we can measure this.
