Material for making Milk as Glue

1. Milk
2. White vinegar
3. Baking soda
4. Pan
5. Water
6. Strainer

Procedure
• Heat 1 and a half cups of milk in a pan, once warm add 3 teaspoons of white vinegar.
• Keep heating and stirring the mixture and you should see the curds ( solid part ) and whey ( liquid part ) separate.
• Strain the mixture using a sieve. You should be left with solid lumps which you can mould together to make a ball.
• Place the solid mixture back in the pan and add a little water and a tablespoon of baking soda.
• Heat the mixture until it starts to bubble.
• Give it a good stir and let it cool. You can now use it as glue. You might need to add a little more water or baking soda until you get the right consistency. It should look like a thick paste.

Introduction
Glue is a sticky material (usually a liquid) that can stick two or more things together. Glue can be made from plant or animal parts, or it can be made from oil-based chemicals.
The first glues may have been natural liquids that come out of trees when they are cut. Later people learned to make glue by boiling animal feet, cartilage or bones. Some very strong glue was first made from fish bones, rubber.
This glue will stick pieces of paper together. Many kinds of art can be made using glue. A collage is a work of art made by using glue to stick colored things onto paper.
Some glue can be used to keep water out of boats, buildings or vehicles. In this case the glue may be called caulk. Some man-made materials, including wood-like materials, are made using glues to bind together small pieces of material or powders.
While many types of glue are safe, certain kinds of glue contain strong-smelling chemicals. Some people sniff these glues to get high. Sometimes people breathe in the vapors by mistake. This is a very bad idea because these chemicals are often poisons and may cause brain damage or illness.

Statement of the problem
The Milk might not be sticky or effective as the commercial glue and to know what kind of milk will be used in this project.

Hypothesis

Objectives
-To be able to use the right kind of milk of making glue.
-To be able to produce a glue by using milk.
-To be able to make the milk and flour sticky as the commercial glue.

Significance of the Study
This research project is important in order for us to determine for to know that there are different kinds of glues and have a product which can be a potential source of income.

Scope and Limitation
This projects aims to create a glue using milk and to make it sticky. This project also aims to create a product which can be a potential source of income. This project is only limited in knowing the effectiveness of the milk to be glue.

Definition of Terms
• Cartilage-Joints between bones e.g. the elbows, knees and ankles
• Stick-to put things together
• Poisons- a substance that causes injury, illness, or death, especially by chemical means.
• Caulk- To make watertight or airtight by filling or sealing
• Oil-based- made with oil as the main substance
