Could a Dropped Snowball Create This Bizarre Sound?

Clark Reisch and his friends were having a bit of a dull night recently, so they decided to drop a snowball off the top of a building, and were amazed at the result. This video appears to capture the bizarre noise that the snowball made upon impact – but some people online are questioning whether the sound heard in the footage is real. What do you think?Reisch told Storyful his theory was that the echo travelling up the wall gave the landing its unique sound effect. Credit: YouTube/Clark Reisch
