Whether you are cheering at a cricket stadium, watching the latest movie with your friends and family, popcorn has been one of the beloved snacks for most of us.

Have you ever thought what’s going on inside the microwave or inside the pressure cooker as this tasty treat pops up?

So what makes a popcorn pop? And why doesn’t each and every corn pop when heated? The answer is a matter of simple science. Popcorn is a special type of corn that pops and turns into a popcorn.

What is a popcorn?

Popcorn is a type of flint corn but it has its own shape, size, moisture content and starch level. Popcorn has a hard exterior shell and a soft starchy centre.

Inside each kernel of popcorn there exist a small droplet of water which is protected by a hard shell which is known as the hull. When the corn is being heated, the water inside the corn also starts heating, as a result, the water turns into a steam, which builds pressure inside the kernel. When the hull or the external shell can no longer hold the pressure inside the kernel, the kernel explodes, the steam inside the kernel is released and the soft starch inside the popcorn get inflated and spills out, which cools down immediately.

Around 212 degrees the water turn into a steam and changes the scratch inside the kernel into a superheated gelatinous substance. The kernel or the hull continues to heat to about 347 degrees. The pressure inside the popcorn will reach 135 pounds per square inch before finally bursting the hull open.
