Rewrite the textbooks on water's surface tension

Rewrite the textbooks on water's surface tension





Prof Angus Gray-Weale from the Chemistry, Department of Chemistry University of Melbourne said, "The surface tension of water affects its behavior and changes with pH but previous research about the adsorption of various ions at the interface all ignored the presence of the hydroxide ion and its charge."

Droplet Dancing




These guys from Stanford did some surface tension research with water and polyethylene glycol (PG).  Watch the video.  My favorite is when they use sharpies to make a hydrophobic barrier and sort different coloured (with different concentrations of PG) to sort the droplets.  The video show specifically how the water and PG droplets interact with each other and surrounding vapour on a glass surface.   Chasing, sorting and other events take place in this awesome soundtracked video.
