Using a milk-based recipe, learners create "moo glue" which is basically white school-type glue. The "secret ingredient" in milk that helps make glue is a chemical called casein. By combining vinegar and milk, learners separate out solid curds made of casein. Then they combine the curds with baking soda to create glue. Adult supervision is recommended for this activity.
