To start out with you are going to heat up 1 cup of milk to almost boiling in a saucepan or microwave it for 90 seconds.

Hint: I suggest using non-homogenized milk if possible for better clumping

Take the pan off the heat and add 4 Tablespoons white vinegar and stir for 1 minute. You will see the milk separate and clumps form.

This is what you are left with. Once they are cool enought to touch you can rinse the milk chunks and then press them together. Now wrap them in a paper towel and sqeeze out any extra water.

You have two choices of WHEN to color your milk plastic. Put a drop or two of food coloring in several small bowls and pour the milk in them just after you’ve added the vinegar; stir. Or you can add it once you have rinsed the chunks and squeezed out the extra liquid; you can also add in glitter.

Vinegar and milk chemical reaction

Wondering about the science?

No, this milk and vinegar experiment does not produce real plastic. You made a substance called CASEIN which occurs when the protein in the milk meets the acid in the vinegar. As the casein in milk does not mix with the acid, the molecules move to join forces to make the casein plastic which forms a plastic-like blob that you can strain and mold.

When the plastic is dry, it is hard, shiny, and durable.
