The Balvenie

Photographer Ernie Button explores the stains left behind when various liquors evaporate. This one comes from a single malt scotch whisky by The Balvenie. The stain itself is made up of particles left behind when the alcohol and water in the whisky evaporate. The pattern itself depends on a careful interplay between surface tension, evaporation, pinning forces, and internal convection as the whisky puddle dries out. (Image credit: E.

Quick-Drying, Fast-Cracking

Water droplets filled with nanoparticles leave behind deposits as they evaporate. Like a coffee ring, particles in the evaporating droplet tend to gather at the drop’s edge (left). As the water evaporates, the deposit grows inward (center) and cracks start to form radially. After just a couple minutes, the solid deposit covers the entire area of the original droplet and is shot through with cracks (right).

Researchers found that the cracks’ patterns and propagation are predictable through a model that balances the local elastic energy and and the energy cost of fracture. They also found that the spacing between radial cracks depends on the deposit’s local thickness. Besides explaining the patterns seen here, these cracking models could help analyze old paintings, where cracks could hide information about the artist’s methods and the artwork’s condition.

"#TheApprentice": the #film #ConvictedFelon #DonaldTrump doesn't want you to see

A new #movie about #young #DonaldTrump hits #theaters Friday, despite Trump trying to block its release. It paints an #unflattering #portrait of his #rise as a #realestate #mogul — and Republicans are calling it #election #interference.

The scenes are based on #IvanaTrump's #divorce #deposition in 1990, in which she detailed a 1989 #sexualassault.
