In our today's world its important to know what is plastic,what is its use,how it can be used,and how it cause problem to us and our beloved earth.
So in this session iam going to have a discussion about creating a simple mode of natural plastic and its decomposition.
This may or mayot be a natural plastic,but quite useful.
I has thought to write it when i had read about it in one of my teacher's practical book.
This is a simple,silly and unrealistic matter.sometime you may know about it already.
Needed materials:
- 2 glass jars
- 4 ounces(120ml) of whole milk
- 1 teaspoon of vinegar
- small plastic charm
- 2 clay flower pots
- soil
Now see how:
Pour 4 fluid ounces of whole milk into a saucepan and heat.The milk will first boil,then seperates into tiny particles(curds) and a clear liquid.Using the pot holder,slowly pour off the curds into the other glass jars.
Add 1 teaspoon (5ml) of vinegar to the curd and allow the mixture to stand about 2 hours.The indivitual curds will be seen to melt into a solid yellowish mass at the bottomof the clear liquid.The mass consists of fat,minerals and the protein casein-a string like molecule that bends like rubber until it hardens.Pour out the liquid and carefully remove the mass from the jar,kneading until it has a dough consistency.
Mould your plastic into any shapes placing them on a shhet of waxed paper to dry overnight.
