Milk Plastic (casein)🥛🤯

 Hello everyone.

This week in Science, Chemistry we are trying to make milk plastic. Which is also known as Casein. Here is what we've been doing so far.

Aim:

I want to find out how to turn milk into plastic


Method:

    Equipment:
  • Stove/Oven/Microwave
  • Measuring Cup
  • Measuring spoons
  • Milk (1 cup)
  • Pot/Bowl (microwavable container)
  • White vinegar
  • Paper 
  • Spoon
  • Mug
  • Food colouring , glitter, cookie cutter (optional)
    Instructions:

  1. Get all equipment
  2. Pour 1 cup of milk into your pot/ microwavable container.
  3. Heat the milk in the microwave or on on the stove until it is steaming.
  4. Add 4 teaspoon of white vinegar to a mug.
  5. Add the hot milk to the mug with the vinegar.
  6. Stir the mixture of the milk and vinegar with the spoon.
  7. Stack 4 layers of paper towels on a surface that is safe to get damped.
  8. Scoop out the curds with the spoon and place them on the paper towels
  9. Fold the papers towel over the curds and press down to absorb the extra liquid .
  10. Knead all the curds together and shape it to a ball of dough.
  11. Color, shape or mold the dough. Colour your doah with food colouring.(Optional)
  12. Put all the milk plastic creations you have made on a paper towel and let them dry overnight.
  13. Now you have made Milk Plastic.
What is casein? 
Casein which is a latin word which means 'cheese' is a protein also found in other dairy products. This is why casein might be considered as a dairy product. When milk is heated and combined with acid such as vinegar the casein molecules reorganize into a long chain. The substance it ends up into is the same as  plastic and which involves with this experiment.
