first, pour desired amount of kernals in the brown bag...(a lot goes a long way!)

like so...

fold the bag..it doesn't have to be taped or anything!

put the bag in the microwave..

if you have a popcorn button, press it. if not, put the popcorn in for about 1:45-2:00 minutes

and, waahlah! you have popcorn! if any kernels didn't pop, then just take the popped ones out, and put the kernals bak in the microwave.
