A soda can is a cylindrical container typically made of aluminum or steel, designed to hold carbonated beverages like soda. These cans are lightweight, durable, and easily recyclable, making them a popular choice for packaging drinks. They usually have a pull-tab or a can opener mechanism for easy access to the beverage inside. Soda cans come in various sizes, with the standard size being 12 fluid ounces in the United States. The exterior of the can is often printed with colorful designs and branding, representing different soft drink companies. Cans are sealed to maintain carbonation and freshness until opened.
