Description

Glue contains water as well as polyvinyl acetate, a much longer and more flexible chemical compound. These long, flexible molecules move through the water like strands of boiled spaghetti. When the food coloring drops are added, the combination of water and polyvinyl acetate molecules prevents them from spreading widely.

Objectives
In this lesson, students must be able to mix all of the colors and then let them react with the dishwashing soap while waiting for the exciting outcome of their experiment.
