Seeing Sound Waves

When Garth Brooks performed “Shout!” an inauguration party earlier this year, you can literally see the sound traveling through the crowd as the audience throws their arms up when they here the word “shout.” This isn’t a prank, but I thought it was a super cool video, and maybe someone can think of a way to use this in a prank?
