The Magic Bag

The Pencil and Baggy Experiment

In this fun STEAM learning exercise, you will learn about polymers! A polymer is a molecule that is made from joining many small molecules together. Plastics are polymers that are made up of long strings of molecules that are flexible. When you poke the pencils through the baggy, the polymer hugs the pencil creating a seal around it!

  • Baggy (Ziploc is best)

  • Water

  • Sharp pencils
