for the love of popcorn

A few years ago when I was on the angel food cake and popcorn diet (also known as Weight Watchers Points) I bought a microwave popcorn popper. It's a thin plastic bowl with a lid and a magic paper liner thing that goes in the bottom of the bowl that does something to make the popcorn pop. The paper liner looks pretty much like a mini paper plate and is good for a few pops but then it gets kind of burnt and you have to change it. I stocked up on the magic liners because popcorn was/is a staple of my diet. And, I don't like salty packaged microwave popcorn and I was afraid of my airpopper thanks to the time sparks came out if it. I loved my microwave popper EXCEPT that since there was the paper liner thing, I had to put the popped popcorn in another bowl to spray my fake butter on it. I was going through a lot of bowls. Still, I used it religiously.
A couple weeks ago I ran out of the paper things. I went to buy some and could not find them anywhere. So I googled them and found a lively discussion among foodies about microwave poppers. One guy was also upset that he couldn't find the liners and another guy called him a blithering idiot because all he had to do was put his popcorn in a brown lunch bag and microwave for a few minutes until the popping stopped.
WHAT?! NO WAY! I was a blithering idiot, too, because I had no idea. Luckily I had a bunch of brown lunch bags left over from a time I was making bag journals! I put 3 tablespoons of popcorn kernels in the bag and folded the top over twice. I put it in the microwave for 5 minutes and the popping slowed at about 3 minutes. I took the bag out and it was full of popped popcorn!  Popped popcorn without cancer causing chemicals! OH MY BUDDHA! I drizzled some melted butter right into the bag and shook it up. No bowl needed.  Life just got so much better (and easier).
I searched foodtv.com and see that Alton Brown has a method for this too but his way involves oil and a stapler.  You don't need the oil to make the popcorn put but I bet his recipe tastes amazing. I also didn't staple my bag and it stayed closed.
I wonder what else I don't know.
