Aim: To find out if you can make glue from milk.
Materials: 100ml of milk
White vinegar 25ml
Baking soda 5g
Two 250ml beakers
Stirring rod
Spatula
Bunsen burner
Tripod, gauze mat and heat proof mat
Filter funnel and filter paper
Matches
Two pieces of paper
Method: 1. the tripod, gauze mat, and heat proof mat were set up. The Bunsen burner was then lit.

2. A 250ml was filled one third and milk was then added.
3. 25ml of vinegar was then added to the mixture.
4. The mixture was then slowly heated while being stirred consistently. Once white clumps (curds) were seen the burner was turned off. 5. The filtering apparatus was set up.

6. The mixture was poured into the filtering equipment until all liquid (whey) was separated from the curds. 7. The way was then poured into the sink.
8. Curds were then put back into their original beaker and one spatula of baking soda was put into the mixture. 9. The mixture was stirred and then put on a two pieces of paper and then stuck the two pieces together. Results:

In the experiment it was found that milk glue is strong enough to stick two pieces of paper together. It doesn’t take long for small curds to form but you should wait longer for the big curds. Discussion:
