Surface Tension - Part 2: Milk Swirls

The video tutorial explores the concept of surface tension and how it can be reduced by adding soap. It provides a step-by-step demonstration using milk, food coloring, and dish detergent to create colorful patterns. The tutorial encourages experimentation by changing variables like the type of milk used. The demonstration is safe and easy to perform, making it an engaging way to learn about surface tension and chemical reactions.
