Max and Alex enjoyed surprise colour spinners today. The first spinner is coloured in red, green and blue. When the spinner turns fast, brain combines colours making it appear white. The second spinner is Benham’s disk and it does the opposite. It is black and white, but when the spinner turns, you can notice that some lines appear coloured.
