When the day came, Topsy was restrained using a ship's hawser fastened on one end to a donkey engine and on the other to a post. Wooden sandals with copper electrodes were attached to her feet and a copper wire run to Edison's electric light plant, where his technicians awaited the go-ahead.
In order to make sure that Topsy emerged from this spectacle more than just singed and angry, she was fed cyanide-laced carrots moments before a 6,600-volt AC charge slammed through her body. Officials needn't have worried. Topsy was killed instantly and Edison, in his mind anyway, had proved his point.
A crowd put at 1,500 witnessed Topsy's execution, which was filmed by Edison and released later that year as Electrocuting an Elephant.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
