A bubble machine is a device designed to produce a large number of bubbles quickly and efficiently. It typically uses a motorized fan to blow air through a solution of soap and water, creating bubbles of various sizes. These machines are popular for parties, events, and entertainment venues, providing a fun and whimsical atmosphere. Bubble machines come in various sizes and designs, from small handheld models to larger, more complex units. They can be used indoors or outdoors and are often found at children's parties, weddings, and themed events. Some machines even have adjustable settings to control bubble size and output.
