Cans are containers made of metal, usually used to store food and beverages. They are designed to keep contents fresh and safe from spoilage. Common examples include soda cans and food cans like those used for vegetables or soups. Cans are sealed tightly, which helps prevent air and bacteria from getting inside. Cans are also recyclable, making them an environmentally friendly option. When you finish a drink or meal, you can simply rinse the can and place it in the recycling bin. This process helps reduce waste and conserve resources, contributing to a healthier planet for everyone.
