This is a really odd one – you have to try it out
If your brain works normally this is v. strange
Attached is a wheel of pink dots which take it in turns to flash
1. If your eyes follow the movement of the rotating pink dot, the dots will remain only one color, pink.
2. However if you stare at the black ” +” in the centre, the flashing do turns to green.
3. Now, concentrate on the black ” + ” in the centre of the picture. After a short period, all the pink dots will slowly disappear, and you will only see only a single green dot rotating.
It’s amazing how our brain works. There really is no green dot, and the Pink ones really don’t disappear.
This should be proof enough; we don’t always see what we think we see.
