The Magic of Water Walkers

Are the insects of the family Gerridae land animals or marine animals? That may be a silly question, because water walkers, or water striders, are both. They live on the surface of water, walking around like that's not a miracle. And they aren't the only insects that can do it. Moving around on the surface of the water is not something they can learn, they have to be built for it. Springtails not only walk on water, but they jump from the water like it's a solid surface, and sometimes give us a gymnastics demonstration while doing it. 

It's all in the science of fluid dynamics, which these bugs understand better than most humans. Ze Frank doesn't mind to explain it to us, long with his usual poking fun at the critters when they get a little awkward. This video is more educational and SFW than most of his True Facts series.
