The term 'Bubble Maker' refers to a job that involves using three different tools: GUM, AERATOR, and AIR. GUM is a type of adhesive used to stick two surfaces together. An AERATOR is a device that adds AIR to a liquid, such as water or wine, to improve its flavor. Finally, AIR is the mixture of gases that make up the Earth's atmosphere. Together, these three tools are used to create bubbles, which can be used for a variety of purposes.
