Question
Somesh put a few drops of vinegar in the milk. What change do you think he observed in the milk after some time? What is this phenomenon known as?

When vinegar is added to heated milk, little white bits should form in the liquid. This is because adding an acid, such as vinegar, to milk alters its pH, causing the casein molecules to unfold and reorganise into a long chain, which results in curdling.
