What puts the chew in chewing gum? What makes lipstick stick? When students want the history behind products and answers to questions such as: Why was there a need? Who invented it? How is it made? How does it work? What is it made of? and more, refer them to CDs, Super Glue, and Salsa, Series 1 and Series 2.
