A popular science demonstration shows that when you overlap the pages of two phone books, they are nearly impossible to pull apart. Since most people do not have two phone books sitting around, we will show you how you can do the same experiment with sticky notes. Sticky notes are much smaller than phone books, so they should be easy to pull apart, right? Try this activity to find out! Read more

Science Fair Project Idea
Have you ever heard that two phone books with the pages interleaved are impossible to pull apart? This might seem crazy, right?

The results might surprise… Read more
