Wiggly Gelatin Treats! | The Science of Food! | SciShow Kids

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?

What happens to gelatin powder when mixed with boiling water?

• It remains unchanged

• It dissolves and changes the water's color

• It forms a solid block

• It evaporates

What is the final state of the gelatin mixture after cooling?

• A wobbly, squishy substance

• A hard solid

• A powdery mixture
