After you drink some Scotch, there's usually a thin film of the liquor left clinging to the bottom and sides of the glass. If you leave it out overnight, it'll dry and be a pain to wash off in the morning. But the same dried booze leavings can also be the beginnings of some really lovely art.
Ernie Button takes photos of the waving, swirling patterns left behind on Scotch glasses. This one — part of a series called Vanishing Spirits — is a picture of glass that once held a nice measure of Balvenie.
The idea for this project occurred while putting a used Scotch glass into the dishwasher. I noted a film on the bottom of a glass and when I inspected closer, I noted these fine, lacey lines filling the bottom. What I found through some experimentation is that these patterns and images that can be seen are created with the small amount of Single-Malt Scotch left in a glass after most of it has been consumed. It only takes a very thin layer of Scotch to create; the alcohol dries and leaves the sediment in various patterns. It’s a little like snowflakes in that every time the Scotch dries, the glass yields different patterns and results. I have used different colored lights to add 'life' to the bottom of the glass, creating the illusion of landscape, terrestrial or extraterrestrial.
Interestingly, there was a recent article that was published in the Journal of Nature (I think) by Dr. Peter Yunker on the Suppression of the Coffee-Ring Effect by Shape-Dependent Capillary Interactions i.e. how are coffee rings made. I contacted him to see if he could see any obvious connection between the two liquids and the rings / patterns they create. He got back to me and unfortunately could not explain what was happening with the Scotch.
That paper Button mentioned was published in 2011. It explores the physics of particles suspended in liquid — not just coffee, but lots of things. Turns out, if you put a drop of liquid on a solid surface, it will tend to dry in a circular shape. As it dries, anything suspended in the liquid will migrate to the outside of the circle. If you put a drop of coffee on a table and leave it to dry, what you'll get is a round spot ringed by a narrow band of dark coffee gunk.
Why does the gunk form a ring, instead of evenly covering the whole circle? Yunker's research showed that it has to do with the shape of the particles that make up the gunk.

This illustration of a flea comes from Robert Hooke's Micrographia — an amazing collection of illustrations drawn from microscope images, first published in 1665. Think of it like a proto-viral blog post that somehow fuzed Nature and Buzzfeed. Something with a headline like "15 UNBELIEVABLE IMAGES OF EVERYDAY THINGS!"
Micrographia — the whole thing — is now available in ebook form. For free. In several different formats. To give you a sense of why this is worth checking out, here's Carl Zimmer on the book's social/scientific impact back in the 17th century:
In January 1665, Samuel Pepys wrote in his diary that he stayed up till two in the morning reading a best-selling page-turner, a work that he called "the most ingenious book I read in my life." It was not a rousing history of English battles or a proto-bodice ripper. It was filled with images: of fleas, of bark, of the edges of razors.
The book was called Micrographia. It provided the reading public with its first look at the world beyond the naked eye. Its author, Robert Hooke, belonged to a brilliant circle of natural philosophers who--among many other things--were the first in England to make serious use of microscopes as scientific instruments. They were great believers in looking at the natural world for themselves rather than relying on what ancient Greek scholars had claimed. Looking under a microscope at the thousands of facets on an insect's compound eye, they saw things at the nanoscale that Aristotle could not have dreamed of. A razor's edge became a mountain range. In the chambers of a piece of bark, Hooke saw the first evidence of cells.
Hooke gave a lecture to the Royal Society about these investigations, and the members of the Society were so impressed that they urged Hooke to publish a book--a visual argument for the new scientific method.
