My 6 year old has autism and his hyper fixation is anything space related and comparing sizes of everything in it from molecules to galaxies. So needless to say finding this book hit every one of his interests and he’s hooked. Not only is the book cute and clever, the hidden secret at the end of the book sent him into a fit of giggles while searching for everything with his black light pen. This is the only book he constantly goes back to.

Loved this book!

Format: Hardcover

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.
