Ying Yin

Materials: bioplastic
Ingredients: gelatine, agar, cornstarch, eggshells, tea grounds, sesame powder, water
Processes: boiling, drying, freezing
Tools: pan, spoon, molds
Timeline: 3 weeks

In those experiments, I tried to make use of some kitchen wastes to make some stable and strong bioplastic. I mixed all the ingredients with water and glycerin and boiled them for several minutes to form a thick liquid. After putting the liquid into the molds, the only thing left was waiting. It took me about one week to get all of them dried out. I also tried to freeze some of them. The texture of the frozen pieces got hard and stronger, and the bubbles inside the piece got much more visible than the others.
