How It Works
Normal plastic is made from oil, which is unevenly distributed on Earth and is a non-renewable resource. Scientists are working on ways to make plastics from renewable resources. The bioplastic we produced is made from corn (corn starch), a renewable resource. The vinegar we mixed in caused a chemical reaction that modified the corn starch and formed a new substance. The glycerin kept it from drying out. This shows one of the ways scientists are creating bioplastic from renewable resources.
