Ive never been a huge fan of popcorn! it always gets stuck in my teeth I see. Well, did you know that the popcorn puff is 20 to 50 times larger than the original kernel? That's pretty big. How long has popcorn been around. Remnants have been found that date back to about 3600 BC. Popcorn has really been aruond that long? What an intereseting fact.
