Скачать или смотреть How to Turn Milk into Plastic? | Science Experiment

A kids chemistry experiment to find out the reaction of milk when it is heated up and combined with an acid, such as vinegar. When the milk combines with the vinegar it forms curd called casein molecules. The casein molecule is a monomer and the chain of casein monomers is a polymer. The polymer can be scooped up and moulded, which is why plastic made from milk is called casein plastic.

Is casein plastic still used today?
Believe it or not, the protein casein is still used to make plastics today that are used for items like fountain pens. In fact, there are many people who collect the jewellery, buttons and buckles are made from Casein.
