Why do some beaches squeak and what's the deal with singing sand dunes? I went to Australia to find out. Along the way I lose my marbles, get sunburned, and fill my camera with sand.

[@redman2751]

I have squeaky sand on the beaches in NC. I’ve found that if the sand has had a couple days to settle and the top layer is slightly hard while the bottom layer is soft and then I sort of kick my foot forward as I step the sand will squeak. My kids love it.

[@anthonycolbourne4206]

Exactly what I have found. After it rains, somehow the rain helps to compact a tight layer crust. After some time a day or two later, that crust dries out, and if you walk through that undisturbed layer and scuff your feet mainly through the crust layer, you get that squeaky sound

[@Bob_Adkins]

When I was a youngster, there were several small rivers and creeks in my area that had clear water and large, dry, blindingly white sand bars in the turns. We could easily identify the sand bars that would squeak (we called it "barking" because it sounded like a seal vocalizing). We instinctively knew why it squeaked, the grains were clean, dry, and mostly round quartz. We could also see a slight electric glow on dark nights, and we thought the piezo action also had something to do with the sound.

[@throughcolouredglasses9300]

Wait *what*?? Electric glow? I am so intrigued, would you mind elaborating for someone who grew up in the city and has never seen a desert in real life?

[@Bob_Adkins]

@@throughcolouredglasses9300 Well, this was in Louisiana, not even close to being a desert. The sand must be clean, of pretty uniform size, and very white, indicating its mostly quartz. When shuffling our feet vigorously in the sand, we got the noise and a very faint glow (on a dark night) obviously caused by the piezo effect. I assumed it was at least partly responsible for the squeaking sound. I hope that helps!

[@jakipop3397]

The editing and the special effects in this are really clean.

[@mcchuggernaut9378]

I first encountered this phenomena on vacation as a child at Hilton Head island beach in South Carolina. Above the tide line, when conditions were just right (usually slightly windy days), scuffing my feet through the sand produced a high-pitched swishing "squeak/whistle". I always assumed that was due to friction and the grains rubbing together quickly. This was a very interesting more in-depth explanation of why it makes this sound. Thanks!
