YouTube filmmaker Cory Williams was walking around Alaska with his girlfriend when he stopped to skip a stone at a frozen lake and discovered the “coolest sound ever.”
His jaw dropped when the rock hit the icy surface. The rock made a cool noise, which sounded kind of like a laser or chirping bird. Williams was NOT expecting this — and his reaction is priceless. Mother nature is so cool!
“This is the coolest sound I’ve ever heard!” he says to the camera, before running to grab another stone, so he can hear the sound again.
