Challenged by her professor to make art using double replacement reactions, chemistry student Catalina Larson delivered. To Larson, the reaction of FeSO4 (iron sulfate) and NaOH (sodium hydroxide) to make Fe(OH)2 (iron(II) hydroxide) stood out, reminding her of the Robert Frost poem “Nothing gold can stay.”

Nature’s first green is gold,
Her hardest hue to hold.
Her early leaf’s a flower;
But only so an hour.
Then leaf subsides to leaf.
So Eden sank to grief,
So dawn goes down to day.
Nothing gold can stay.
