This blue dot brain teaser has had us all amazed in the office this week! Watch the video below and follow the instructions. If you look at the blue dot for long enough, something amazing will happen!

TIP: Don’t move your eyes at all after the picture changes to black and white or it won’t work as well

What can you see when you look at the picture? Does the black and white picture turn to colour? We couldn’t believe our eyes when we tried it and it worked for us!
