YouTube user DudeLikeHELLA (real name, Cory Williams) documents his life in Alaska and shares the videos he takes online in a series called “Living in Alaska.”
Two days ago, he uploaded the 43rd installment in the series to his channel, which depicts the outdoorsy dude skipping rocks on a frozen lake.
The video is called Coolest Sound Ever because Williams discovered skipping rocks on a frozen body of water produces a weird, alien-esque sound.
The best way to describe noise is a sort of metallic chirping that echoes.
Williams was not expecting to hear what he did, and he freaks out after he realizes what a cool noise the rock skipping made.
Though the entire video is 16 minutes long, the rock-skipping part is only about two minutes and starts at 3:41 — check it out for yourself.
