Colour Mixing, Spinners and Optical Illusions

We have been looking at how coloured food dyes mix and make new colours.

Today we looked at mixing the colours of light.

We did this with coloured spinners, a motor, a battery and two wires.

We tried mixing two primary colours, all 7 colours of the spectrum, and our own individually designed spinners.

The results were very impressive!  Mesmerizing!

We also made our own fidget spinners (and spun them on cocktail sausage sticks), and we spun drawings on pencils to fool our brains into thinking that two individual pictures were part of a single picture.

Fascinating!
