Summary
"Plastic made from milk" —that certainly sounds like something made up. If you agree, you may be surprised to learn that in the early 20th century, milk was used to make many different plastic ornaments —including jewelry for Queen Mary of England! In this chemistry science project, you can figure out the best recipe to make your own milk plastic (usually called casein plastic) and use it to make beads, ornaments, or other items.

This project idea was developed and written by Sandra Slutz, PhD, Vice President of STEM Education, Science Buddies.
