Optical Illusions

Optical Illusions published by DK is a fantastic activity book filled with pages of illusions along with activities and how they trick our minds.

I bought this book for my daughter to read while on a very long road trip.  She adored it and it kept her busy for hours figuring out how everything worked.  It was a perfect car book.

I recommend this book for readers 7 and up.  It's a great gift book for older kids.
