Water Is Thicker When You’re Smaller

The video explores how microbes in the microcosmos feed using cilia-driven vortexes, creating a whirlpool effect to draw in food. It introduces fluid dynamics, focusing on the Reynolds number, which determines whether movement is dominated by inertia or viscosity. The video explains how microbes move in syrup-like water using cilia and flagella, despite the high viscosity. It discusses the impact of viscosity on microbial life and ecosystems, and how microbes navigate human bodies, affecting health. The video highlights the importance of understanding microbial movement in various environments.
