explanation: "When milk and an acid mix together, the milk begins to change properties. The milk begins to separate into a liquid and a solid. The solid material consists of minerals, fat, and a protein called casein. This protein is made of long molecules. Those molecules allow us to bend the lumps like rubber until it hardens and resembles plastic." - AustinKids.org
