What makes popcorn so special?

The key to popcorn is the unique design of its kernels. Most importantly, its kernel consists of a very hard, mostly nonporous outer shell called pericarp. The reason why popcorn pops is the water trapped inside its kernel. If the kernel is heated to a high enough temperature, this water will transform into steam.

Can popcorn pop your stomach?

It takes a lot of heat energy to raise the temperature of water, and then there is the problem that the popcorn is mixed in the stomach fluid. Boiling popcorn kernels hydrates them. They can still pop, but they won’t be fluffy or airy. So most likely you won’t pop the kernels, and at most you get “half-popped” popcorn.

Why does popcorn cool so fast?

Until it pops! The popcorn pops! Because of the enormous pressure build up the sudden expansion of the gas will puff up the starches within the kernel. Once the gas has escaped the popcorn cools down quickly. As a result, the starch turns solid again and holds onto its shape.

Is popcorn an explosion?

As the kernel heats up, the water expands, building pressure against the hard starch surface. Eventually, this outer layer 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.

Can two year old have popcorn?

Remember, children under four may not have all their childhood molars and are still learning this skill. Popcorn. Again, this is a risk due to a young child’s inability to chew well. If you’re wondering when babies can eat popcorn, it’s best to hold off until around the age of four.

Why does popcorn not pop?

Popcorn kernels will not pop if they contain too little or too much water moisture inside the kernel. The popcorn kernels which do pop have 14-15\% moisture in the hull and anything less or more will cause the popcorn kernel to not explode.

Why does some popcorn not pop?

Popcorn kernels will not pop if they contain too little or too much water moisture inside the kernel. The popcorn kernels which do pop have 14-15\% moisture in the hull and anything less or more will cause the popcorn kernel to not explode. You can test the moisture of your popcorn by using your fingernail.

What makes popcorn pop?

People may not have always known what makes popcorn pop, but humans have been enjoying popcorn for thousands of years. Ancients attributed popcorn’s magic to tiny gods trapped within the kernel that would burst with anger when heated, but we now know that the real reason why popcorn pops is a fascinating mix of chemistry and physics.

Why does a kernel of popcorn burst when heated?

To understand why a kernel of popcorn bursts when heated, we must first understand the construction and composition of a corn kernel. The outer, light yellow, transparent hull of the corn is the secret to popping corn. When intact, the hull is impervious to moisture and key to creating the pressure needed to pop the corn.

Why can’t Corn Pop?

Not all corn can pop. The other three familiar types—sweet, the kind we eat on the cob; dent, the kind used for animal feed and in processed foods; and flint, the decorative kind you see at Halloween and Thanksgiving—don’t have thick enough or strong enough hulls to contain the pressures necessary to liquefy the starch before bursting, Rappel says.

Why do you put popcorn kernels in the microwave?

It absorbs the microwaves, which raises its temperature high enough to cook the kernels by conduction. In order for this to happen properly, the kernels should be positioned over the susceptor. The next time you want to make some popcorn snacks, peek into the empty bag.
