Homemade Glue

In this video tutorial, Dr. Boyd, a chemist, guides viewers through the process of making a simple glue using gelatin, sugar, and water. The video explains what constitutes a glue, including both natural and synthetic types, and demonstrates how to test the adhesive properties of the homemade glue using note cards. Safety considerations are minimal as the materials used are non-harmful. The tutorial provides a step-by-step guide to mixing the ingredients and testing the glue's effectiveness.
