Natural Pigments and Dye Extraction

The video tutorial explores the use of natural materials to create pigments and dyes, highlighting their historical significance and providing a step-by-step guide for experimenting with these materials. It emphasizes safety precautions and the need for adult supervision when handling hot water and potentially poisonous plants. The tutorial concludes with a preview of testing the dyes in the next part.
