How to make sneaky plastics
Buy 1 Litre expired milk from kumsiojui
use ah ma's cooking pot
use ah ma's spoon
vinegar
strainer
jar
paper towels or toilet paper
Pour expired milk into pot and heat, let milk warm but don't boil,
add a teaspoon of vinegar and stir the mixture. Soon, clumps of
solid material will form on the suface, continue stirring.
Place strainer on top of jar and pour mixture thru strainer, use
spoon to press the clumps and squeeze out the liquid, which is
discarded. Remove the material and place it on a paper towel or
toilet paper to dry. Mold sneaky plastics with your hands and let
it dry for 1-2 days before use.
The solid material that has formed is called "casein" which
seperates from milk when an acid like vinegar is added. "Casein" is
used in the industry to make glue, paint and some plastics.
