Probably no one has ever remembered to drink a combination of milk and Red Bull, and that might not be a bad thing either.
You’ll see what happens when you mix these drinks, the result is more disgusting than you probably expected, and the secret is in chemistry.
Casein is a protein found in cow’s milk. The energy drink has the acid that causes neutralization of this protein. Therefore, when mixed, instead of separating (such as water and oil), casein begins to accumulate, causing milk clotting and forming a solid state. Look how it looks.
