Chromatography as Art

Hackaday reports that chromatography—a chemistry technique that separates mixtures using paper or powder—is being transformed into art.

The process is straightforward enough for a classroom project or home experiment: just a sketch pen, paper, a coffee filter, a glue stick, and a few other household items. It's a perfect bridge between art and science, and while it makes striking visuals, it also has practical applications—the same technique can measure caffeine content in your morning brew.
