I thought this was fake

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. --------- II --------- Thanks to Vlogbrothers for their sponsorship of this video.

I explore the world looking for interesting engineering stories which explore complex issues in interesting ways. In between episodes I'm doing a PhD in space robotics at MIT. My website is https://www.atomicfrontieronline.com, I occasionally tweet from   / atomicfrontiers  , and you can join the Atomic Frontier Discord server to talk about cool engineering stuff at   / discord  . You can help support my work and see some cool behind-the-scenes content at   / atomicfrontier  .
