You most likely know that a venomous snake’s bite can kill you in a matter of seconds, but do you know what actually happens when the venom starts swimming through the bloodstream? This video demonstrates what does venom from a Russell’s viper do to the human blood and I must say it’s some pretty scary stuff. Only a drop of venom can do unimaginable damage and lead to an agonizing death. So if you ever come across a snake and you’re not sure it’s not venomous, don’t try to pet, don’t get close to it trying to take pictures; just run in the other direction as fast as you can!
