 So when this is coming up towards the rattlesnake, they see the pants and the foot, and it looks like my leg is stepping on them. Kale started taking the fake leg with him on hikes. And whenever he came upon a rattlesnake, he would, very carefully, step on it. And then I'd record their behavior. I mean, I recorded their rattling. I recorded their tongue flicking. I recorded everything they did. And then I gathered that data. By Kale's count, he stepped on 175 rattlesnakes, and only six attacked the fake leg.
