Colour Wheel Top

 j

Looking further into primary and secondary colours-we created Colour Wheel Tops, from 'You'd Never Believe it but, A Rainbow is a Circle.

'  

To start, these tops involve a bit of fraction math; dividing a circle into 6 equal parts. Every other part is coloured a primary colour; red, blue, yellow. The sections between represent the secondary colour made by the primary colours on either side.

 
We then mounted these are cardboard and poked the center with a pencil to serve as a spinning top. Your brain is supposed to register white when all the colours are swirling together-although reports varied!
