Chewing gum blowing is the act of creating bubbles with chewing gum. This is done by chewing the gum to soften it and then using air pressure from the mouth to expand a thin layer of gum. When the gum is stretched and filled with air, it forms a bubble that can grow larger until it pops. The process requires a specific technique, including the right type of gum, often a softer variety like bubble gum. The ability to blow bubbles can vary among individuals, and some may find it easier than others due to factors like mouth shape and gum consistency.
