The video explores the properties of gelatin, a dessert that behaves like both a solid and a liquid. Through an experiment, the teacher demonstrates how gelatin can be squished through a colander, highlighting its unique characteristics. The process of making gelatin from powder is shown, explaining how it dissolves in hot water and forms a wobbly, squishy substance when cooled. The video concludes by discussing gelatin as a colloid, a mixture of solid and liquid properties, and compares it to other substances like oobleck and slime.

What is the main purpose of using a colander in the gelatin experiment?
