Watch what one drop of snake venom will do to your blood

We all know to avoid poisonous snakes, but what does their venom actually do to our bodies? This video — which shows what happens when venom from a deadly species known as the Russell's viper comes in contact with our blood — is absolutely bone-chilling. The vid shows a handler extracting the deadly liquid and adding a drop of it to a glass of blood. After just a few seconds, the venom transforms the blood into a thick, disgusting jelly. The effects of venom vary by species, but you'd better believe we'll be opting for long pants on our summer hikes from now on.
