Understanding Chewing Gum

The video explores the unique chewiness of gum, focusing on the mysterious 'gum base' ingredient allowed by the FDA. It delves into the history and chemistry of various substances used in gum, including natural resins and synthetic polymers. The video also features an experiment to create gum using natural ingredients like mastic gum and beeswax, highlighting the differences between natural and synthetic components.
