I *never* was able to see the 3D. There were a few times that I *almost* felt it was about to pop but then poof, it would go awayI was waiting for somebody to ask. Hahaha They're 3D books - SO cool!! Here's one of them - there are several. You have to look at them and then "hopefully" you'll see the 3D effects. I've had them for years and they're so much fun to pass around.
