. . . because we now know that an electric eel can light up a tree. Noeel, folks! https://www.npr.org/2019/12/04/784854604/noeel-electric-eel-lights-up-christmas-tree-in-tennessee An electric eel in Chattanooga, Tenn., is sparking a little holiday cheer. Every time Miguel Wattson the electric eel releases a jolt of electricity, a festively-decorated Christmas tree next to his tank at the Tennessee Aquarium flickers and glows. "There is a sensor directly in his exhibit that picks up when he produces electricity," Aquarist Kimberly Hurt, who cares for the electric eel, tells NPR. The aquarium had already connected the sensor to a soundboard and a light board to correspond with Wattson's bursts, says Hurt. "It'll light up the board. It also does make some noise so people can hear when he's producing electricity." So it wasn't a huge leap to also have Wattson's sensors connected to a Christmas tree, for a seasonal spin on the display.
