intermolecular forces

Bubble, Bubble, Toil and Trouble

In this Activity, students first create a standard bubble solution by mixing water with liquid dishwashing detergent. They then add different substances to samples of the detergent solution. The solutions are compared to see which produces the longest-lasting bubbles. The Activity is a fun way to introduce the concepts of surface tension, intermolecular forces, and the use of surfactants.
