Light is everywhere, even in a dark night. Interestingly, it could be seen by eyes, but never captured by anything. The phenomenon of refraction happens when light goes through different substances. Combining refraction and certain conditions, these results in various colours and forms. By experimenting on the refraction of light passing through different types of mixed liquid, this project tries to create concrete images of light, and in effect, brings new aesthetics to light products.
# Liquid mixing
Chemistry has proven that both substances—water and oil—do not mix. However, due to polarity, each could dissolve its own corresponding dyestuff. It is also interesting to note that different types of oil do not dissolve with each other. Delightful results were produced throughout the experimental process of mixing different types of liquid and putting them through a light source. The different colours, varying densities and transparency of the mixed liquid yielded beautiful graphics within the entirety of the liquid itself.
In the experiment a tablet box mad from acrylic glass material was made to fill the liquid. During the sinking process, water was observed sinking at a relatively faster pace and creates a clear border at the oil-water interface. Comparatively, the pigment sinks very slowly and instead creates a gradient in the oil part. The two different movements of the coloured liquid toys precisely with the fluidity properties of liquids. It inspires the creation of a moveable graphic of light that can then be concreted by liquid.
With a desire to trigger movements only by the motion of rotating, the light box was thus inspired to take on a symmetrical cubic shape.
Upon rotation, the fluidity of colours and shapes sparks a simultaneous movement of light. Standing for a long time, the light presents a still status with the blue remaining at the bottom while a thin precipitated pigment of red layer maintains above. Eventually after 48hours, the slightly coloured upper layer would turn white due to the complete precipitation of the pigment. With a desire to trigger movements only by the motion of rotating, the light box was thus inspired to take on a symmetrical cubic shape.
