Optical Illusions Make You Wonder if Seeing is Believing

Optical illusions are really cool. In fact, one of the neatest  things in the world is when our eyes play tricks on us. They say 'seeing is believing', but you can't always believe what you see. I invite you to take three minutes out of your day and enjoy a few optical illusions. Are these things moving, or are your eyes being deceived?

It's probably a good idea to play the video on full screen, and feel free to pause the video if your eyes need more time to fixate. Have fun!
