Question

what makes popcorn pop???

Answer 1

when you heat the corn, the water inside gets hot and expands. as this happens it puts pressure against the walls of the corn. then once the pressure is high enough, POP CORN! =]

Answer 2

Popcorn" is an ancient type of corn that contains a hard, glassy (or "vitreous") type of starch on the outside, and a softer, "floury" starch on the inside. In fact, it is probable that popcorn was the original type of corn, and that the first human use of corn grain as a food item ocurred when people realized that when they parched this grain, a formerly hard kernel became soft and edible.

Most of the inside of a kernel is composed of starch, which is a storage carbohydrate, or fuel. This starch is known as the seed's "endosperm" (meaning it is inside the seed). Its purpose is to provide energy for the living part of the kernel, the "germ" or embryo, once this embryo germinates and establishes a new plant. Starch has a large water holding capacity, and for this reason it has a number of industrial uses as a dehydrating agent in powder form. When you heat popcorn, the water that is ordinarily bound in the floury endosperm becomes a vapor and bursts through the fruit case, or "pericarp" of the kernel. In order for this to happen successfully and dependably, therefore, the kernel must be relatively small, and the hard, or flinty, outer shell of the kernel must be quite strong to resist the building pressure. This is why popcorn produces grains that are smaller than most field corn.

Answer 3

Each kernel of popcorn does contain a small drop of water stored inside a circle of soft starch. (That's why popcorn needs to contain 13.5 percent to 14 percent moisture.) The soft starch is surrounded by the kernel's hard outer surface.

As the kernel heats up, the water begins to expand, and pressure builds against the hard starch. Eventually, this hard surface gives way, causing the popcorn to explode.

As it explodes, the soft starch inside the popcorn becomes inflated and bursts, turning the kernel inside out. The steam inside the kernel is released, and the popcorn is popped

Answer 4

"Popcorn" is an ancient type of corn that contains a hard, glassy type of starch on the outside, and a softer, "floury" starch on the inside. In fact, it is probable that popcorn was the original type of corn, and that the first human use of corn grain as a food item ocurred when people realized that when they parched this grain, a formerly hard kernel became soft and edible.

Answer 5

As the kernel is heated, the water inside boils. When it boils, it expands a large amount, creating pressure inside the kernel. Eventually this pressure is enough to pop open the kernel and puff it up into popcorn.

Answer 6

Because of the heat that make the moisture inside the corn the get in form of vapor, this vapor press out from inside to out side making the corn to pops.

Answer 7

I found you a great answer to the question -- from NASA! Briefly, the water in the kernels turns into steam and causes the kernels to explode.

Answer 8

moisture locked in a tight skin,that explodes with the heat

Answer 9

moisture in the corn vs th heat in the pot

Answer 10

i had homemade pop corns ytd! yummy!
