The desert dunes that sing when sand moves
HERE’S THE INTERESTING PART
Deep in the Namib Desert, the massive sand dunes actually sing. When the wind blows or footsteps cascade down the slope, the friction between millions of perfectly dry, spherical sand grains produces a loud, resonant booming sound that echoes for miles. It sounds like a low-flying propeller plane, a haunting natural acoustic marvel that completely defies expectations.
One discovery leads to another.
