Making Plastic At Home

Take a pan and put some milk with cream in it. Boil it and then add some vinegar to it and stir gently. Add a colour and continue the stirring. After sometime the mixture starts becoming rubbery. Now take this substance and wash it in water. This is home made plastic.

Emulsion At Home

Take some oil, half an ounce of vinegar and some mustard. Mix all of them together in a glass vessel. This becomes an emulsion. This mixture will separate into its different components immediately after the stirring is stopped. Each layer will be separate and will show it. Likewise full cream is an emulsion from which butter and cream separate on keeping.
