Crown Splash Sealing
A sphere falling into water generates a spectacular crown splash at the surface. The object’s impact ejects a thin sheet of fluid that rises vertically. The air pulled down into Keep reading
Crown Sealing
Objects falling into a liquid pool create a beautiful splash, and, in this beautiful, award-winning video, the Splash Lab explores a peculiar instability that occurs just as the splash closes. Keep reading
The Fluid Dynamical Sewing Machine
Anyone who has poured a viscous fluid like honey or syrup will have noticed its tendency to coil like rope. A similar effect is observed when a viscous fluid stream Keep reading
Viscous Dripping
Artist Skye Kelly’s “Creep (strain)” sculpture shown above is made from toffee. The viscous fluid deforms under the force of gravity, resulting in elongated drips and slow jets that buckle Keep reading
