Advertising Chewing Gum Bad Breath - Inspiration Photoshop
Chewing gum is a soft, cohesive substance intended for chewing but not swallowing. Humans have used chewing gum for at least 3,000 years. Modern chewing gum was originally made of chicle, a natural latex. By the 1960s, chicle was replaced by butadiene-based synthetic rubber which is cheaper to manufacture. Most chewing gums are considered polymers.
