Reader Reviews

EXCELLENT!
There are lots of optical illusions to try out in this amazing little pack! I like all of them so much I can't tell you which is my favourite.

AWESOME!
I have these and they are perfect for my science fair project with my partner, they give you the answer as to why this illusion bothers the human mind and our scientific question is how do optical illusions influence the brain.
