This document provides instructions for making a bioplastic at home using common ingredients. It is a 5-step process: 1) Gather supplies like cornstarch, vinegar, glycerin and water; 2) Combine ingredients in a pot and heat, stirring continuously, until thickened; 3) Once thick, turn off heat and pour onto foil to cool; 4) Mold into a shape while still warm if desired; 5) Allow the plastic to fully dry for at least two days before use. The mixture becomes a plastic film through a chemical process where the acetic acid and heat modify the cornstarch.
