This glue was used as far back as early Egyptians who used it in the construction of their boats. This same glue was used on some World War 1 aircraft. Let's make some of our own and see if it works!

 

Glue making activity:

• Pour 50ml of milk into a beaker and gently warm it until it has just started simmering.

• Add 5ml of vinegar and watch as the milk separates into curds (solid) and whey (liquid).

• Filter the curds through a cloth with small holes in it (or a sieve).

• Put the curds into a small container and add 5mls of ammonia solution.

• Heat and stir the mixture until a thick creamy liquid forms. This is the glue.

• Allow the glue to cool.

 

After you've finished:

From here you can put your glue to the test. Use your glue to help build a small house made of sticks, add objects to a poster or collage, or for any other project that you need glue. How well did your homemade glue stick objects together?
