Viscosity at Home: A Quick Thickness Test

Added: 2026-05-06

[00:00:00]In this episode, a simple viscosity experiment uses household liquids to show why substances pour at different speeds.

[00:00:08]Safety first. Wear goggles, work on a tray, and keep spills away from electronics as you compare water, vegetable oil, and corn syrup. The steps guide measuring a fixed drop height, dropping marbles, and timing drainage through a narrow funnel. Viscosity is the internal resistance to flow caused by molecular interactions. So, syrup pours slower than water and oil. By the end, viewers will predict pouring speeds from viscosity and notice thickness from a steady stream.
