How do you make a puff adder—the snake that causes the most snakebite fatalities in the whole of Africa—even more more scary? Weirdly, by slowing down its attack in super slow-motion.

This video by BBC Earth shows the adder, which as the coolest Latin name of Bitis arietans, leaping toward a water balloon. At first, you think that the snake's barely moving,. Then, even slowed down dramatically, it surges forwards at remarkable pace. If this thing chooses to bite you, you probably don't have much choice in the matter. A shame, then, that it's probably the most common and widespread snake in Africa. [YouTube]
