Hunter's comment

I like this product because it's very creative. A pop-up book is no longer just a work of art, but a functional one.
The official site has a description about this book:

Paper Engineer Kelli Anderson, who also created the pop-up This Book is a Camera in 2015, now takes the concept of pop-ups with real functionality to a whole new level. The result is a surprising and beautiful book with stylish pop-ups that all have different functions like a musical instrument with strings, a spiralgraph, a decoder ring, a perpetual calendar and a speaker that amplifies the sound of your smartphone.

You can learn something new while you play. Every page is a new surprise, let you learn science, education, and fun while reading the book. I think it's a wonderful educational tool for kids.

Functions:

There are six functions in this book

1. Instrument

Use the yellow pick attached to the top left corner of the page or your finger to play the strings.

2. Decoder

Use the decoding ring to add the message you want to convey or decode the message you received.

3. Calendar

4. Planetarium

Turn on the flashlight function of the mobile phone and put it under the planetarium in the dark. The planetarium will project the autumn northern hemisphere constellation diagram on the ceiling.
