response: I see. Well, did you know that the popcorn puff is 20 to 50 times larger than the original kernel?
original_response: I love it!  I love watching it burst as the hot air as the hot air expands.
history: Ive never been a huge fan of popcorn! it always gets stuck in my teeth
knowledge: The kernel ruptures and forcefully expands, allowing the contents to expand, cool, and finally set in a popcorn puff 20 to 50 times the size of the original kernel.
