This Lego pop-up book might not be the biggest or most complex build, but it’s quite ingenious.
In the video above you can see how the book – built with Lego bricks – opens to reveal an inner pop-up world. The book uses a mechanism that pulls up the structure when the book is pulled open and relaxes it when the book is closed.
Watch the video above to see the Lego pop-up book in detail. You can also visit the Lego IDEAS website by clicking here, to see more projects by other creators. You can use the filters on the right to browse the collection.
