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.

The hardest part of web design can be nailing down the look. These days, even non-designers can easily spot a stale stock photo or lazily-made icon. What’s the solution?
