Something that I never really knew about before reading this book was echolocation. There has been so many times that I have tried to navigate my way through my own house in the dark, and still would bump into things, even though I have lived here for 21 years. I watched this short clip on YouTube about a boy named Sam. He has been practicing echolocation for five months and it was incredible to watch. I enjoyed reading the book, but seeing Sam use echolocation definitely made me more interested. I started thinking more about all the individuals that use sounds to play baseball, and even how swimmers that are visually impaired are able to swim with blacked out goggles on. Sam said that because his vision is impaired, his other senses are a lot stronger. Another video I watched focused on blind swimming. The swimmer talked about brushing his arm against the rope to feel if he was going straight. He had to use touch in order to guide himself. Using other senses to make up for the impairment of another is truly an amazing thing that we are able to do and it is amazing to learn about. I have learned that our brains use reflected sounds to perceive properties of silent objects.
