Step-by-Step Directions

Now, let’s get down to the nitty-gritty of making your bioplastic. Remember to take your time and enjoy each step. Here’s how it unfolds:
- Mix the cornstarch and water in a non-stick pot.
Start by combining your cornstarch and water until there are no lumps. You want a smooth mixture that blends well together. - Add white vinegar and glycerin, stirring until combined.
Pour in the vinegar and glycerin. Both of these ingredients will help the mixture become more pliable. Stir until everything is fully mixed. - Place on low heat, stirring slowly until the mixture thickens and bubbles.
This is the magic moment. As you stir, pay attention to the texture it will start to thicken. Watch for bubbles forming, as that indicates the bioplastic is coming together. - Remove from heat and pour onto a baking parchment or silicone mat while warm.
Carefully transfer your thickened mixture onto the baking parchment or silicone mat. Being warm makes it easier to spread, so don’t worry if it’s a little sticky; it will cool down quickly. - Allow to cool completely before shaping.
Let your bioplastic sit until it cools completely. This might take around 30 minutes, but it’s a good time to clean up your space or plan what shapes you want to form. - Store creations in a cool, dry place and reshape as necessary.
Once your creations are cool, store them in a dry spot. They can be reshaped later if needed, so don’t feel like everything must be perfect right away.
