Using some easily obtained household items, it is possible to turn milk into plastic
Ingredients:
- Milk
- Vinegar
- Food Colouring
- Jar
- Sock or stocking
- Biscuit cutter
Method:
- Heat the milk over a low heat on the stove, don’t let it boil.
- Add a drop or two of food colouring, and stir.
- Add two tablespoons of vinegar, and stir until clumps form.
- Place the sock or stocking into the jar, and secure the top around the top of the jar.
- Pour the milk and vinegar mixture into the sock/stocking, and allow the liquid to drain through into the jar.
- Squeeze excess liquid out of the lumps, and then press the lumpy material into a biscuit cutter.
- Allow to dry for two or three days
Results:
- When we added the green food colouring to the milk it turned slightly green.
- When we put the vinegar in, the milk went lumpy.
- We strained the liquid out of the lumpy bits, and pressed the lumps into a gingerbread biscuit cutter
- The lumps were soft and squishy, and had turned darker green
- We let it dry, and it turned hard, and went even darker green.
