It turns out some people can use echolocation to find their way, did you know that? As bats use mostly sound waves to help them navigate through the treacherous nights, the blind are beginning to learn how to do just that very same thing. Take this man, who’s made it his mission to teach every blind person the best way to get through this harsh world without any extra technology. Impressed? Give it a watch. You just might be able to learn how to use this technique yourself!
