Start by gathering all the necessary ingredients: starch (like tapioca or cornstarch), water, vinegar, and corn syrup as an alternative to glycerin. Each has an important role—starch forms the base, vinegar acts as a preservative, and glycerin adds flexibility. We used a clean metal bowl and spoon to avoid contamination. This cleanliness helps ensure that our utensils are safe and durable.

In the bowl, combine the starch and water in a balanced ratio—usually about 1:2. Then, we added a teaspoon of vinegar and a small amount of corn syrup (around ½ teaspoon). Stir well until the mixture becomes smooth and milky, with no lumps. Considering all these factors, ensures a consistent mix which improves a better final texture for our biodegradable utensil.

Pour the mixture into a non-stick pan and heat it over medium heat. Stir continuously to prevent it from sticking or forming lumps. After a few minutes, the mixture will begin to thicken and turn gel-like—this is when the starch is activating. The consistency should resemble glue. Be patient—this step is key to forming a strong and flexible material.

While the mixture is still warm and pliable, spread it onto a mold or a flat surface lined with parchment paper. You can also pour it into spoon or fork-shaped molds if available. Flatten it evenly using a spatula or your hand (with gloves). Leave it to dry for 24–48 hours in a clean, ventilated area. This drying period is crucial for hardening the utensils.
