There are certain species that can walk on the surface of water. Don't try this at home, because humans and most animals are far too heavy to even attempt it. But these insects have found their ecological niche because there are other species that don't have the same talents, and they can be eaten. These water walkers each use their own different method for moving about on the surface of water: walking, rowing, jumping, surfing, and even a sort of jet propulsion. They've developed these techniques and even specialized body parts to harness the science of fluid dynamics, meaning surface tension and capillary action, to out-maneuver whatever it is they want to eat. Yeah, there's plenty of science here to interest you, but this is also a True Facts video, so you get Ze Frank cracking jokes and making fun of these talented little creatures. There's a 65-second skippable ad at 4:56.
