Step 1: Combine Ingredients
- In a small saucepan, mix together 2 tablespoons of cornstarch, 1 tablespoon of vinegar, 1 tablespoon of glycerin, and 1 tablespoon of water. Stir well until smooth, breaking any lumps.
Step 2: Heat the Mixture
- Place the saucepan on low heat. Continuously stir the mixture as it warms—this is when you’ll notice it beginning to thicken. Keep stirring until it reaches a gel-like consistency.
Step 3: Add Color
- If you wish to add color, now is the time! Mix in a few drops of food coloring until you achieve your desired hue.
Step 4: Pour into Molds
- Once thickened and colored, carefully pour the bioplastic into your heart-shaped molds or use cookie cutters placed on wax paper.
Step 5: Set and Dry
- Allow the bioplastic hearts to cool and set for several hours or overnight. They will solidify as they dry.
Step 6: Remove from Molds
- Gently pop the hearts out of the molds. They should come out easily if they have been adequately set.
- Tips & Variations

- Shape Variations: Use other molds or cookie cutters for different shapes—stars, flowers, or initials!
- Texture Add-ins: Add a sprinkle of glitter or small beads for texture and embellishment.
- Size Options: Adjust the amount of mixture to create larger or smaller hearts as needed.
