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.

Men and women are different in many ways but that doesnt mean that they cant be equal. Both have an equal role in shaping the society.

The truth is, male and females are not equal. Yes, they have similarities as breathing, living creatures. But, in most cases, that's the only thing truly in common. To put this is in a faster written, faster to read way; Mental, physical, religious, ect. views are very rarely ever 100% identical, which very easily goes for everyone regardless of gender. If male and females were truly ever viewed as equal or as the same, society would display that. Father being allowed to play as mother or mother being allowed to play father (in cases, of course), fair pay in different job placements (especially when well-deserved as a huge, main argument), fair treatment, fair appearance in industries, ect. as simple based examples. If they were viewed as equal, there would be no need for feminism and several cases of stand-offs for different rights. Now, of course this doesn't mean it needs to viewed as kindergarten play, "one for her and one for him and one for them." When things are well deserved, the more the better for that person. Male or female. But, regardless of looks or gender, there are times where one gender will hold more dominance than the other. And, throughout the human history, it has been that way. And it does not seem as if there will be much change for that in the future. Long story short: No, male and females are not equal for several different reasons.
