Microwave popcorn is a convenient snack that comes in pre-packaged bags designed for popping in a microwave oven. The bags contain kernels of corn, oil, and seasonings, which heat up and expand when microwaved, creating fluffy popcorn. Most bags are designed to pop in about 2 to 4 minutes, depending on the microwave's wattage. This snack is popular for its ease of preparation and variety of flavors, including butter, cheese, and caramel. Microwave popcorn is often enjoyed during movie nights, parties, or as a quick treat, making it a staple in many households.
