In this activity, learners use geometry in observing the shapes and angles soap bubbles create when they join together. Learners use a cut-up straw and pipe cleaners to make a cube frame after measuring the angles where soap bubbles connect using a print-out protractor. The activity also includes a simple recipe to make your own bubble mixture.
