Take a few seconds to gather the unpopped kernels as you reach the bottom of the bag of popcorn. Put them in a jar or container, and before you know it, you’ll have enough unpopped kernels to make a batch on your own. Place the unpopped kernels in a paper bag and microwave them. It’s crucial to note that because they’ve previously been exposed to heat, popping them in the microwave may require less time. Put some kernels in a paper bag, microwave it for a minute, and you’ll save at least a minute on the regular popping time.
