[00:00:00]What if I told you that this glass of milk can turn into plastic in just a few minutes? Let's find out. Materials: 1 cup warm milk, 2 3 tablespoons white vinegar, a bowl, a strainer, paper towels. Procedure: Pour the warm milk into a bowl. Add the vinegar and stir gently. Watch as the milk starts to separate into lumps and liquid. Pour the mixture through a strainer. Collect the white solid and place it on a paper towel. Press out the extra water. Mold it into any shape you like and let it dry for one to two days. What happened?

[00:00:32]The vinegar reacts with the milk protein called casein.

[00:00:36]The casein separates from the liquid and forms a solid material that can harden into a plastic-like substance. Science behind it. Quin is an organic molecule found in milk. When an acid vinegar is added, the protein structure changes and forms a new solid material. This is a simple example of organic chemistry in action. Mystery challenge. Is it milk, plastic, or both? Comment your guess before the reveal.
