In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products. Learners compare the stickiness of their glue against white glue, a glue stick, and peanut butter using the "stick-o-meter" test.
