1) Get a paper lunch bag.
2) Put in the bag a 1/2 cup of kernels in the bag. I chose these red popcorn kernels.
3) Fold the bag over twice.
4) Put it in the microwave for 2-3 minutes, or until the popping slows to 1-2 pops per second. (My bag took 2 minutes.)
5) Sprinkle with a little salt and butter (we used Earth Balance Whipped Spread). Shake in bag.
