[Spiderman] What happens to the radioactive spider that bit Peter? What was the spider going to be used for anyways?

Always wondered what happened to it. And what was supposed to be the purpose of a radioactive spider? Did anyone know its bite would result in giving the victim powers?

It bit another student named Cindy Moon, who became the hero Silk and the spider then promptly died from the radiation. A student named Carl King, who was at the exhibition, figured out the that spider must have made Peter Spider-Man and tracked down the spider and ate it. The resulting mutation turned him into the Thousand, a collection of 1,000 spiders. 

The spider wasn't intended to be radioactive. It was caught in a lab demonstration accidentally, so nobody knew that it existed until after it bit Peter and Cindy.
