How Popcorn Pops

Popcorn is a tasty addition to any movie night but it's also an example of some pretty cool science. Check it out!

How Popcorn Pops - The Wet Truth

Although popcorn kernals may look totally dry, each kernel of popcorn actually has a tiny amount of water inside it. This water is stored inside a circle of soft starch inside the kernel's hard outer surface. As the kernel heats up, the water's molecules start to move faster and get farther away from each other; this molecular expansion is the same reason water turns into steam when you boil it. As the water expands it puts pressure against the hard starch. Something's gotta give - so eventually the water pressure wins out and the popcorn ruptures. The soft starch inside becomes inflated and bursts, flipping the kernel inside out to release the steam inside! Mmmm, popcorn!

Popcorn - Did U Know?

  • Don't freeze popcorn or keep it in the fridge. This dries out your kernels and without moisture there won't be any poppin'.
  • Those kernels you find at the bottom of the bowl that failed to pop are called old maids. They were too dry to have any pop left in them.
  • The English colonists were introduced to popcorn at the first Thanksgiving feast in 1621 when Quadequina, brother of Wampanoag chief Massasoit, brought a deerskin bag of popped popcorn to dinner as a gift.

@rainbowpoptart Well, I'd have to disagree with you there my friend. Naturally the audience that buys Barbie dolls are young girls. At a young age and with multimedia today girls are highly influenced by what they see on the TV, Magazine, and you guessed it their toys. Seeing is believing and with the unreachable beauty standards you see in magazines, it's kinda hard for girls to not want to pursue to be skinner and the likes. But anyway, your right with the Barbie being independent woman that don't need a man. But I think this new line is showing that all types of girls can be independent. This new line is expanding its skin colors, giving different hip sizes and different heights and different types of hair styles. It's no longer the blond haired and blue eyed type of deal. I think this is representing that there are many different kinds of people and different kinds of shape a sizes. With the television showing perfect fictional girl characters, or models on magazines, and other places, I think that it's good that they're showing different body types.

@urifour11  I don't disagree with that. Well, not entirely. I disagree with your Barbie comments. Pink is Barbie's everything, and making something not pink for the female Barbie dolls would be a bit.. not Barbie.  I don't like their changing of the body shapes all too much. Barbie is supposed to be an exceptionally good-looking woman who shows girls that they don't need a man to be happy with their lives (though some people may think otherwise because of Ken's existence) and that they can do literally whatever they want to. It sounds really harsh, but I think it's the individual's fault for thinking they need to look a certain way to be accepted.  Although I strongly disagree with the newer dolls, I do completely respect why they're doing it. I'm sure they're working on the Lego sets. They already have dolls, so Legos should be here any day now, haha. And @Pink_Cool_Girl I want to look into the computer thing you were talking about to continue that discussion, but I'm super busy right now (I'm multi-tasking like crazy ugh). It'll have to wait until tomorrow. :P

@rainbowpoptart  You make a very good point. But what I think PCG is trying to say is that maybe someone should consider that some girls don't like pink? Like, I loved playing with doll houses as a kid AND toy cars. But what if someone made a black Barbie house. Like hell yeah I would buy that. Or maybe a pink you car. Wouldn't that be cool? Maybe what I'm trying to get at here is that companies could mix and match their toys together. Use different colors for different items. That would help expand their market much more.  What I'm really impressed though is what Barbie is doing at the moment with making different body types for their dolls. That's awesome right? Anyway, if a girl wants to get a toy car then she can just waltz her way to the boys section and get one. Sure it's kinda disregarding that maybe a girl would like a toy car but man, that's not stopping her from buying that sweet toy car. But what we should really be focusing on is how LEGOS did the sexist thing. WHY ISNT THERE A BATGIRL LEGO SET OR A WONDERWOMAN LEGO SET?!? THATS WHAT IM WAITING FOR AND IM 13 YEARS OLD BUT I WOULD MOST DEFINATLEY BUY ANYTHING REGUARDING WONDERWOMAN. A little off topic. Companies would make more money mixing and matching their toys. Blue toy cars for girls Barbies, a cooking grill for boys. And then there are things that are for both genders like science sets or Doctor kits. In fact I think girls play more with Doctor kits than boys tbh. What one saying is, companies could expand more.
