Xtreme Illusions 2: Mind-Blowing Illusions, Wacky Brain Teasers, Awesome Puzzles (National Geographic Kids)

Fun book, my daughter loves to do these and fun her and my wife have to wind down before bed

This book was extremely disappointing. I couldn't seem to make 90% of the illusions work. I thought perhaps it was my eyes, but my friend couldn't either. I had planned to use this for an object lesson with my class, but this is a dud. Sorry I purchased this book and wonder what I'm going to use for my lesson. I wouldn't recommend it to anyone.
