Remember the pop-up books from our childhood? They consisted of pulling a tab and a barn door disappeared to reveal cows and horses inside. That was complete shit compared to this pop-up book.

You’ll open the pages of this book to erect a paper planetarium, working instrument, speaker, decoder, and more cool things. After the $1 off coupon, you’ll pay just $20 for this book, the best Amazon price we’ve seen in a year (it usually sells for around $27). Plus, it would make a great gift for kids and adults.
