popcorn is a puffy 2 gram protien food.it is made from a kernal that it is cooked and is turned from its inside to make a softer more edible food. it is made of palm oil, salt 2% of natural artificial flavor, tbhq, and citric acid for freshness. smartboy#8
popcorn is a puffy food cooked from a kernal, and while the kernal is cooked it is turned to the inside which forms a softer more edible food smartboy8
Popcorn expands from a corn kernel and puffs up when heated. Corn is able to pop because its kernels have a hard moisture-sealed hull and a dense starchy filling. Which other grains don't have. This allows pressure to build inside the kernel until an explosive "pop" results.
i found this information from: http://en.wikipedia.org/wiki/Popcorn
Popcorn is corn kernels that pop when exposed to very hot dry air. It is a very common american snack and is eaten a lot when watching movies. Well first lets start out with why and how popcorn pops. Popcorn pops or explodes because each kernel has water inside with soft starch on the hard outer layer. The popcorn kernel is actually 13.5 out of 14 percent moisture. When the kernel gets heated up, the water starts to expand and cause pressure on the hard outer layer. Soon the hard layer weakens and causes the kernel to explode and turn inside out! Then the popcorn has been popped. Now there are also two kinds of popcorn kernels. The "butterfly" and the "mushroom". The butterfly is lighter, larger, fluffier and appears to look having a pair of wings. The mushroom is more the opposite of the butterfly. The mushroom is densely pacted into more of a ball shape. The mushroom popcorn is used for camelizing because the butterfly would most likely break if carmelized. Popcorn has been popular in the U.S. from around 1890 to today. It is sold at the theaters and the super market and carnivals. Microwaviable popcorn is very popular and the first microwaved popcorn was in the 1940s but was not used in homes yet. Today the average american eats around 58 quarts of popcorn a year!
To begin with, popcorn is a special type of corn grain, generally not edible like other styles of corn like white or yellow corn on the cob. It is typically stripped from the cob and then heated in a pan until the inside literally breaks through the tough hull, creating fluffy, crunchy kernels.These kernels were found by Archeaologists popped form, that carbon dating show that it is 1000 years old. Therefore, the Native Americans were one of the first people to enjoy popcorn.
The relationship between science and popcorn is that temperature affects popcorn.Popcorn goes pop because as you heat it up the moisture inside also gets hot and would likely to turn into steam. However, the hard outer coat of the kernel can support up to 10 atmospheres of pressure, stopping the water expanding into steam. The water keeps heating up above 100°C, building up more and more pressure. As it heats up, the moisture in the kernel alters the starch stored inside forming a kind of jelly.
Then the water inside the kernel heats up and tries to boil, applying huge pressures to the shell. Eventually this ruptures and the water rapidly boils, forming a foam.As all the water in the starchy jelly has now boiled off the starch dries out, becomes hard and can support itself even when the popcorn cools down and the water condenses again.After that, foam cools and forms the popcorn.
First, popcorn has been around for many decades, even centuries, and dates back to the ancient Egyptians. They used barley as corn. From reading these articles, I found out that the term "corn" is actually just a slang term that meant that this crop was popular in the area. In America, maize was popular so that is why this was called corn. Now, corn is a general term. I read more and learned that the most popular form was "popping." I also read that the ancient Aztecs performed many rituals that were based on maize (corn). This was common knowledge, but it answers the question. Lastly, I read that the explorer, Cortes, found maize (corn) when he invaded southern America. The interesting part was that I took notes on this explorer, but did not read this part. To really answer the question, it is simply a product of maize (corn). It is made when it is cut off from the main cob and is then heated to the point where the inside of the kernel bulges out and forms a puffy and soft look (and taste!). My last website was incredibly helpful because it really explained the process. This article explains how the starch and oils inside the kernel expand, but cannot properly because the boiling liquids cannot pass through the kernel. It bulges out, as I mentioned earlier, forming the puffy texture. Lastly, the popcorn "turns inside out."
I forgot to mention that the kernels only expand when it is heated and is affected by temperature (even natural temperature because it has occurred in the US before).
When I looked at this question, I thought, Phew its just asking me what is popcorn, but then I realized its not as easy as I thimk, this was a very complicated question to answer.
Before we start getting into different subjects of popcorn, let me tell you the basics about it. The scientific name for popcorn is actually zea mays everta. Weird huh? Popcorn can range in different colors from gold to red to black, and every single little bitty piece of popcorn is different from each other, making them one of a kind! Now that you know these few basics about popcorn, let me give you some incite on the rest of the background history about popcorn.
Well, first, popcorn is a special type of corn grain that is generally not edible untill it is heated in a pan, (or more often a microwave) and when the shell pops off making the edible part inside start to expand. As you can obviously notice, that is why you hear a loud cracking noise when you put a bag of popcorn in the microwave to cook.
Next, did you know that popcorn originated about 1,000 years ago? Well, it's true. The Native Americans were the first people to ever get a taste of this delicious stuff, and soon after that, they introduced it to fellow Europeans.
Lastly, popcorn can come in tow different shapes. One of them would be a snowflake, almost like a cumulus cloud (a little science lesson here) and a mushroom, which pops into a round ball. Even though all popcorns are different, there has to be some kind of similarity in them, right?
Well, now that you have learned so much about how popcorn is made, where it comes from, and how they differ and are alike, you should go try to find some information and your own and add to the prior knowledge that you already have about popcorn.
(p.s. If you notice anything here that should not be here, don't hesitate to argue with me, I'll check back to make changes if I can)

Popcorn is a unique type of corn grain, but it not usually edible like other types of corn such as white/yellow corn on the cob. Popcorn is generally stripped from the cob then heated in a pan (or as we usually do now- warm it up in the microwave)until the inside actually breaks through the hull, creating large, fluffy kernels that we eat today at movie theaters and call popcorn. The type of corn that popcorn is made from is a new world food, but the seeds of it have been found in previous archaeological digs from thousands of years ago.

PS: Do I get credit for my answer? ;)
iluvmusic141: awwww i wish you could get credit but no I don't think so :( thanks for going on the blog though!!!!!
I have a question:Why isnt iluvmusic141 getting awesomespectacular extra credit? I thought if SunnyD posts it that mean you get extra credit?
at magnoliablossom21: yeah if your comment gets posted by us, you do get extra credit, but iluvmusic isn't exactly in our school anymore....
Oh...I thought she was in our school. That clears things up!
