This project aims to create a product which brings the aesthetics of latte art to a higher level. The product will be 4-Dimensional (4D) and consumers would be able to watch a small scale performance when it is placed on water. The product makes use of edible shape memory materials to generate motion of unfolding when placed on water surface. Key materials discussed in this report are Tapioca Starch and Rice Paper. The shape memory effect of the Tapioca Starch Membrane and Rice Paper on water is the key to its unfolding properties. Thus, this report investigates ways to improve the aesthetics such as coloring and flavoring as well as the effect of water content on the material’s shape memory effect.
