A venom container resembles a small, inflated toy balloon except that the wall is made of thicker rubber-like material. The throat of the container is stretched over the end of a shaft that is used as a handle, and the shaft supports a resistive heating element within the container. Poisonous snakes have heat receptors by which they locate accurately warmblooded animals within striking distance. As a snake would strike its prey, it strikes the warmed container and injects its venom into the container.
