A bubble machine is a device designed to produce a continuous stream of bubbles. It typically uses a motorized fan to blow air through a soapy solution, creating bubbles of various sizes. These machines are popular for parties, events, and children's play areas, providing entertainment and visual appeal. Bubble machines come in various shapes and sizes, from small handheld models to larger, more complex units. They can be powered by batteries or electricity and often feature adjustable settings for bubble size and output. Some models even include colorful lights to enhance the bubble experience, making them a fun addition to celebrations and gatherings.
