How to make plastic out of warm milk and vinegar

Hey kids! It is science time. I am sharing with you an experiment i found. Maybe you could try it at home with a little help from your parents.
The idea is that you can make plastic out of milk and vinegar. Yes, as crazy as that sounds. Just make sure the milk is warm and that you dry the mix really well before you start giving it shape, Oh! and be patient with it, let the shapes you make dry properly before you start plying with them, otherwise they will break.  Just put your goggles on and start experimenting!
