Quick Answer: What Makes Popcorn Pop Science Project?

What puts the pop in popcorn science fair project?

Lesson Plan. Popcorn pops because each kernel has a tiny bit of water inside it. When the kernels are heated, the water inside heats up to the point where it exerts enough pressure to burst the kernel open. The soft material inside puffs up as it explodes.

How popcorn is made scientifically?

The characteristic popcorn consistency and white-yellowish foamy appearance results from the starch inside the popcorn kernel. With high temperatures, the starch gelatinizes and then expands with the rapid burst of the kernel. Once it cools down, the solidified flake we know as popcorn is formed.

What substance makes popcorn pop?

Popcorn needs between 13.5-14% moisture to pop. The soft starch is surrounded by the kernel’s hard outer surface. As the kernel heats up, the water begins to expand. Around 212 degrees the water turns into steam and changes the starch inside each kernel into a superheated gelatinous substance.

How does popcorn pop Mystery Science?

Each kernel contains a small amount of water stored in a circle of soft starch inside the hard outer casing. As the pressure builds, the casing eventually gives way, and the kernel explodes and pops, allowing the water to escape as steam and turning the kernel inside out.

Can you pop popcorn over a candle?

put a small amount of oil in the tray and enough popcorn to cover the bottom of the tray. then hold the tray by the canes over the lit candles. it will take a while but the popcorn will eventually start popping. keep over the heat until the popping stops.

Is popcorn a living thing?

Popcorn kernels contain water, as do all living things. When you heat them, the water boils and turns to vapor (gas), but the gas has no where to go because it’s inside of the kernel.

Which country eats the most popcorn?

1. The United States Remains at the Top of the List. First, it should come as no surprise that the United States is still one of the top countries in the world when it comes to overall popcorn consumption.

Is popcorn made from real corn?

The Internet-approved tip is as follows: Soak popcorn kernels in water for 10 minutes, then drain and pop as normal. The theory is that the extra moisture helps produce fluffier puffs.

How is popcorn related to chemistry?

They found that the key factor that appears to influence popping quality is the chemical structure of the pericarp, or outer hull, which is composed partly of cellulose (a polymer of glucose). During heating, the corn pericarp acts like a pressure cooker that locks moisture inside the corn kernel.

Can you hear the kernels pop?

Neither will field corn, the type used in foods such as tortilla chips. Only the kernels from popcorn cobs will pop. Why? They have small, hard kernels that, when heated, trap their moisture until it turns into steam.

Why do kids pop popcorn?

When water gets too hot, it will turn to steam and expand. “Inside each kernel of popcorn is a tiny droplet of water surrounded by a hard shell called a hull. As the popcorn is heated, the water turns into steam, which builds pressure inside the kernel. When the hull can no longer contain the pressure —POP!

Why does popcorn make a popping sound?

Researchers know why popcorn kernels burst open, but they’ve long puzzled over the source of the “pop” sound. When popcorn heats up, the moisture inside turns into steam, building up pressure until the hull splits and fluffy white corn bursts out, often as the kernel sails into the air.
