The exhibit uses the "wick" method of separation in which water is drawn to the centre of a circle of coloured ink drawn on the paper. As the water spreads outwards you see concentric circles of separating colours. In order to standardise the operation the paper is held in a hinged "sandwich plate" which has a template for drawing the circles. The sandwich is then swung through 180 degrees so that the centres of the template holes are brought into contact with the wicks.
For the public it has great visual appeal.
