Using Plastic Wrap For Bananas 

Bananas are usually a favorite for many people, especially children. Not only do they make a healthy and tasty snack, but you can add them to your oatmeal, some cereal, and even on your peanut butter toast. They’re also great to put in salads, but they tend to go bad quickly. Fortunately, there is a way to extend their lifetime. 

You don’t need to wrap the whole banana in plastic wrap, but you should package the stem tightly, so ethylene gas doesn’t escape. By taking this step, you’ll extend the life of your bananas for up to four days.
