They keep the doctor away and power LEDs? Impressive.

Remember those kitschy potato-powered clocks? Turns out, many fruits and vegetables can be used as an electrical conduit—all you need are two different metals (usually zinc and copper) suspended in an acid. Artist Caleb Charland took advantage of the acid in the flesh of an apple to set up this ethereal photo. He wired up 30 small LED lights under a lampshade at an apple orchard in Newburgh, Maine, then got the shot using a four-hour exposure. (It took about 10 apples, wired in series, to light each LED.) As he toldMy Modern Met, “I shot it on an unseasonably warm night in October under full moon light, it was quite a beautiful sight to observe.”
