In this music video for the song “Chocolate Lullaby,” the Macro Room team feature all kinds of fluid dynamical phenomena. It begins with pouring viscous fluids, which, like honey or cake batter, fold and stack before they spread. From there things get significantly less viscous and more turbulent. There’s some neat coalescence, billowing streams colliding, and some gorgeous turbulence. Enjoy! (Image and video credit: Macro Room)
