I have a grandson (5yrs old) who loves "There was an old lady who swallowed a fly" books, and is obsessed with black holes as well. He asked santa for a black hole for Christmas and his mom told me, "good luck with that", so when I found this, it was perfect! He absolutely loved it and it's a cute book to read.

2nd book if you have black light

Format: Hardcover

The book is ok, with the same plot as "there was an old lady who swallowed a fly" but there is a second book that goes back to front if you have a blacklight. Some of the pages were not printed well with the invisible ink but I really liked that second book better, as it explains the terminology like quarks and atoms. It is a fun book but having a black light is a must.
