	This work is based on a research done by MIT media lab that uses organic fluid-based molecules. The molecules anthocyanin, vanillin, chitosan are used as dopants that can sense different pH values. The output is in the form of a broad spectrum of colors, odors and shapes. Based on this, the experiment focus on color changing, using kappa-carrageenan as substrate to present the reaction in a certain form. The outcome shows chemical reactions that are in daily life unreadable and unseen. What is shown here is a new design language to create new appliances. In the exhibition, color changing can be seen both in liquid and solid statues.		This work is based on a research done by MIT media lab that uses organic fluid-based molecules.

	1.1 anthocyanin		1.1 anthocyanin

	Anthocyanins are water-soluble vacuolar pigments. In the 1664 book Experiments and Considerations Touching Colours by chemist Robert Boyle, various edible plants are reported as visual pH indicators due to pH-responsive mechanisms in their tissues [1]. Anthocyanin is a kind of natural colorant in food and beverage industry, and has been found to possess anti-inflammatory antioxidant properties [2]. It has also been researched for use as an indicator for packaging applications to detect spoilage in pork and fish products [3]. All tissues of vascular plants contain the flavonoid anthocyanin, a pigment that changes colour under varying pH solutions.		Anthocyanins are water-soluble vacuolar pigments.
