This sonorous crown started as a scribble on paper. When Lizzy Drew, a high school student at Lin-Wood Public School in Lincoln, New Hampshire, drew a four-pointed zig zag arc on this piece of filter paper and wet the middle of the paper, she saw the ink run and separate into some of its colorful component pigments. The lab assignment Drew was performing involved gauging how various inks behave when eluted through the paper, which is evident here looking at how the Expo marker’s elution resulted in this chromatogram (top), while the Liquid Flare maker (lines at bottom) didn’t separate at all into visibly distinct colors.
