"Her art comes to life by oxidization. Just like apples, bananas oxidize, or turn brown, as the enzymes in their cells are released and interact with the oxygen in the air."

"Cells that are damaged — because they’ve been poked with a fork or dropped on the floor — brown faster. By varying when she applied the marks, Chojnicka discovered that she could create a palette of shades, resulting in surprisingly intricate pictures."

Yes, that gets you an article in The Washington Post these days. Got to keep up with the fads. Speaking of fads, bananas, and "high art," remember the 60s fad of getting high from banana skins and wondering if "Mellow Yellow" was about that? 

Ah, yes, here — Atlas Obscura has an article about it: "Smoking Banana Peels Is the Greatest Drug Hoax of All Time/They called it mellow yellow" ("Donovan would later state definitively that the song was actually written about a yellow vibrator...").

ADDED: I was curious about my use of the word "skins" — "banana skins" — instead of the more normal "banana peels." What came over me? I googled and was very amused to see that "Banana peel" has its own Wikipedia page. It's not just a subsection under "Banana." 

Anyway, there I learn that "banana skins" is the British term. The subsections with the "Banana peels" article are: "Uses," "Culinary Uses," "In a comical context," "Peeling methods," and "Psychoactive effects of banana peels." Under the "comical" heading, we get the serious science of why banana peels provide such a slippery surface:

The coefficient of friction of banana peel on a linoleum surface was measured at just 0.07, about half that of lubricated metal on metal. Researchers attribute this to the crushing of the natural polysaccharide follicular gel, releasing a homogenous sol.
