Electric Eel Powers Christmas Tree Answered
Y'know, I've always wondered about this.
An aquarium filled with exotic fish here is using an electric eel to power lights on a Christmas tree.
Each time the electric eel at the Aqua Toto Gifu aquarium touches a copper wire in its tank, it sends power that lights up globes decking a Christmas tree.
From the Mainichi Daily News. Can't get the link to work to verify, so possibly a hoax.
