As always, Science class with Mr. John is fun! This month we are showcasing our favorite experiment: Teflon Tape Secret Messages! view the guidelines at help desk solutions.
Teflon Tape Secret Message – Polymers
Mr. John wrote a secret message (Go Buckeyes!) on a piece of Teflon tape. When the tape was stretched top to bottom, we were not able to read the message. Once he pulled/stretched the tape end to end, tada! The message was readable! He explained to us that Teflon was a type of polymer and when the tape was stretched top to bottom, the polymers were still bound together, or “hugging”, just not as tightly as when the tape was stretched end to end. Our students loved this!
