How does popcorn pop?: 

How does popcorn pop? By: Chelsey Nichols

Yummy Popcorn: 

Yummy Popcorn Popcorn pops because of three key elements- Moisture (inside the kernel) Starch (inside the kernel) The hard shell (surrounding the kernel)

How Popcorn Pop’s: 

How Popcorn Pop’s When a popcorn kernel is heated the moisture inside the kernel begins to expand,which builds pressure inside the kernel . When the expanding kernel is under enough pressure the kernel explodes through its hard shell, releasing steam (the kernels moisture). As the kernel explodes the starchy center expands and turns the kernel inside out. Creating the white puffy outside and hard kernel shell inside.

Slide 8: 

Fun Facts Popcorn expands to a volume of 40-50 times its original size. Unless there is around 17% moisture in the popcorn kernel it won’t pop efficiently. If there is more moisture the popcorn will be “mushy” ; and if there less moisture the popcorn won’t pop! It’s impossible to pop all popcorn kernels in a bag of microwaveable popcorn, without burning it. Once the majority of the popcorn kernels pop, the internal temperature within the bag drops, not allowing all kernels to heat to the right temperature to explode.
