The Secret of Smart Paper
Brian McCall, Lynn M. Diener, J. Aura Gimm · Journal of Chemical Education · 2009
This activity introduces students to a technology called microencapsulation. In the activity, students learn about special papers that use microencapsulation—such as grocery store receipts, carbonless lab notebooks, and some questionnaires—that they encounter everyday. In this activity students perform a hands-on exploration of three-part carbonless copy paper, learning about the paper through their own personal observations.
