Dancing droplets (audio only)

We’ve all seen dewdrops form on spider webs. But what if they flung themselves off of the strands instead? Researchers at Duke University and the University of British Columbia have now observed this peculiar phenomenon, which could benefit many industrial applications. As long as the strands are moderately hydrophobic and relatively thin, small droplets combining into one are apt to dance themselves right off of the tightrope. The discovery could form the basis of new coalescer technologies for water purification, oil refining and more.
