Burning Bubbles

The video tutorial demonstrates an experiment comparing bubbles made from exhaled gases and methane. It explains the materials needed and the process of creating bubbles with both types of gases. The experiment shows that bubbles made from breath are similar in density to air and do not burn, while methane bubbles are less dense and highly flammable. The combustion of methane bubbles is explained, highlighting the chemical reaction that releases energy. The tutorial concludes by discussing methane's role as a fuel and the need for alternative energy sources.

Explain why methane bubbles are less dense than air.

Describe the chemical reaction that occurs when methane combusts.

What is the significance of methane being a finite resource?
