A kernel of popcorn contains a certain amount of moisture in its starchy endosperm, and when the kernel is heated past boiling point, water in the kernel begins to steam, and generates an internal pressure of about 9 atm. In the tightly sealed popcorn kernel, the steam is held tight by the pericarp. Pressure in the begins to start build until the pericap ruptures, causing a small explosion.
The force of the explosion causes the kernel to turn inside out, and because the moisture is evenly distributed throughout the starchy endosperm, the sudden expansion turns the endosperm into an airy foam. This gives the popcorn its unique texture.
The average popping temperature for popcorn is around 175 degrees celcius. Special varieties of corn are grown to give improved popping yield.
Popcorn ears dating back 5,600 years were discovered in bat caves in New Mexico by Native Americans in 1948.

That is good information know i an use it on my homework(in my own words dont woryl.o.l) thanks
Though popcorn will pop at temperatures as low as 250F, it pops much better at temperatures over 450F - the pop is much more explosive and results in a larger flake (flake = piece of popped popcorn). You can see some vids of popcorn popping in super slow motion here http://www.youtube.com/user/JustPoppinDotCom
It looks really cool when you can actually see what's happening as the popcorn pops.
