Physicists Figure Out Why Honey Falls In Twists

A stream of honey falls onto a freshly baked buttermilk biscuit. Before you devour this breakfast treat, you might notice that the honey you poured formed a wavy pattern on the biscuit's surface, an unintentional decoration for your morning snack.
Most people might think 'huh, that's weird' and then eat the biscuit. But some physicists who noticed the weird twists and turns of honey have taken it upon themselves to figure out why honey and other viscous liquids sometimes take such a strange and winding road towards a moving surface.
