No microphone? No problem! At least not for this high school student! She was singing the National Anthem before a high school basketball game and for some reason, she was not given a microphone. But that wasn't really an issue, because she has one of those voices that just fills up the room, no matter how big.
Check out the video below. Notice how she starts out pretty soft, but within seconds, her voice is echoing off the walls of the massive gymnasium! Incredible!
