Fluid Thread Patterns Thin threads of fluids show how conveyor
belt speeds control fluid pattern behavior in both experiments
and models. A thin thread of viscous fluid (translucent threads
at left) is poured onto a moving belt, creating a dazzling array
of intricate patterns. Simulations (gold threads at right)
reproduce this rich and complex behavior, confirming the
accuracy of a theoretical model developed to describe the
phenomenon. Reporters and Editors Reporters may freely use this
