If you preheat your microwave before putting in the bag of popcorn, not only does the popcorn pop with full intensity but there are very few unpopped kernels

Here's how it works: 1) . Preheat microwave (run the microwave empty for approximately 3-5 mins) 2). insert microwave popcorn and pop as usual (time will probably be cutdown by a bit so keep an eye out). ofc you're wasting power during the preheat but the satisfaction of a completely popped bag is worth it, mine only had like 10 kernels left. You can't preheat a microwave, that is not how it works. by cooking your popcorn for 10 extra seconds will achieve the same effect, you obviously have no idea how a microwave works.
