Inseparable Books

Enrichment Activity for 5-11 11-14


What you need

  • Two very similar books, with at least 100 pages each

Instructions

  1. Carefully, and evenly, interweave the pages of the books son that they overlap to about the middle of the page
  2. Hold the books by the spines and pull!

Results and Explanation

Friction is the force that acts against the motion of two surfaces in contact. The friction between the just two pages is tiny, but with lots of pages in the books, the force becomes very noticeable.

These experiments have not been specifically safety tested for home use but we believe them to be safe if the instructions are followed. Adult supervision or direction is recommended as appropriate. All experiments are carried out at your own risk.
