As with all of Michael Willis' books, this was very enjoyable for both me and my 7-year old nephew.He liked the idea of a hole where things disappeared and laughed when all the animals started showing up in other places.  He was a little confused by the wording used to throw the animals into the hole, but with some explanation, he quickly understood and I think it was a good learning lesson for new vocabulary.The only thing that he didn't like was the picture of the worm at the end because it wasn't something that he had seen before.  I think it was interesting and I understood it because it was dressed up as Einstein, but it was probably too complicated for a second grader.Overall, though, cool book and good to introduce kids to the idea of black holes.
