What age is this suitable for?

This encyclopedia is designed for children aged 6 to 12. The questions and answers are written to be understood by younger readers while being engaging enough to hold the attention of older children. Many parents read it alongside their kids and find themselves learning something new too.

How is this different from a regular encyclopedia?

Standard encyclopedias present information as dry facts organised by topic. This book is built around questions, the exact questions curious kids ask out loud. Every answer explains the how and the why in a way that builds real understanding rather than surface level memorisation that disappears the moment the book is closed.

Why Most Kids Stop Being Curious and What This Book Does Differently

Standard encyclopedias tell children what happens without ever explaining the how or why. That surface level knowledge vanishes the moment they close the cover. A child's brain thrives on connecting ideas across subjects, not memorising isolated facts. The 100k WHYS is built around the questions children actually ask out loud, the bizarre, the wild, the genuinely surprising ones, and answers each one in a way that builds real understanding that sticks. The conversations it starts do not end when the reading does.

The Book That Competes With a Screen and Wins

If a book is not visually engaging and genuinely interesting, it will always lose to a tablet. The 100k WHYS was designed with that reality in mind. Vibrant illustrations, surprising questions on every page, and answers that lead naturally to the next question. Parents report children choosing it over screen time within the first week. Not because they were told to, but because the book is genuinely more interesting than whatever they were watching. That is the standard every children's book should be held to, and almost none of them meet it.

    Put down the iPad for this

    "I left it on the counter without saying anything. Two days later I found her curled up on the couch reading about the Mariana Trench instead of watching YouTube. She has read it twice now. Worth every penny."

    Started conversations I never expected

    "Bought one for my son and ended up ordering two more for my nieces. Hearing my 7 year old casually explain photosynthesis to his grandfather over dinner was a proud parenting moment. It teaches them how to be curious."

    Best gift we have ever given

    "My daughter's teacher pulled me aside to ask what changed. She went from tearing up over difficult problems to saying let us figure this out. The shift happened within two weeks of having this book. Cannot recommend it enough."
