1. Only one way to find out.

Does microwave popcorn KNOW that its microwave popcorn?

2. They found 2,000 year old popcorn in Tutankhamun's tomb

They popped it and it was still OK.

3. no expiration code or date on a box of popcorn bought last spring

it just popped in a shorter time than recommended - but it taste fine

4. Not sure

The actual popcorn would last indefinitely, but I am not sure about the shelf life of the oil or flavorings in it.

5. to everything, turn turn turn . . .

All things must pass

With unpopped microwave popcorn, I'd worry more about the oil and the additives than the corn.

6. So long as you leave the feeding tube in it should be ok

7. Oil can go rancid, popcorn is probably good

Popcorn will keep indefinitely if it doesn't get wet.
