Ok, girls! Ready for this week’s Smart Girl Challenge?
This question seems simple, but see if you can be the first one to answer it correctly. See these two books? Why can’t you pull them apart? To answer this question, try the following: Separating Books
Question: How come you can’t pull the books apart from each other?
To figure it out, try this “science project” approach, as follows:
What you need:
2 identical paperback books
1. You want to insert the two books together about 4-5 pages at a time. The quickest way to do this is like a riffle shuffle.
2. When you have fully interleaved the books push them together so there is an overlap of about 2-3cm. The hold the two books by their spines and try to pull them apart. You can’t! Why?
First girl to get it right gets the prize! We’ll announce the winner next week. Good luck, girls!
How the iTwixie Smart Girl Challenge works:
