How do you make popcorn with a popcorn machine?

Well, usually you set the timer on the machine, then pour in the popcorn kernels and wait until the machine is done.

You forgot to add the oil. Without the oil the popcorn kernels won't pop.
user
Oh yeah! That's really important!

Do you have anything to add?
