Echolocation
Echolocaton what bats use to get around. They scream and then (if) their voice comes back they know that something is their. Here is a example:
Tie a rag over your eyes. Get a beg of bounce balls. Throw one in the direction you want to go. If it bounces back imminently then you know something is near (or right in front of you) . If it takes a while to come back, then you know that an object is farther ahead. If the ball doesn't come back, then you are free to walk away. Try to get around your house like this!
Did you know that the U.S military use something similar to echolocation? They call it sonar! (That's why U.S military spends so much money on learning about bats!)
