Not only is it cheaper to make your own popcorn, but it's healthier and tastes better, too. Plus, it's super easy — all you need is a paper bag, some popcorn kernels, and butter. You might need to play around with the amount of kernels that work for your microwave, but the general rule of thumb is 1/4 cup for about two and a half minutes, or until three seconds passes between each pop. Drizzle some melted butter on top and you're good to go.
