Sure! So, imagine each popcorn kernel is like a tiny container filled with a little bit of water inside. When you put the kernels in the microwave and heat them up, the water inside each kernel starts to get really hot.
As the water heats up, it turns into steam, which is like tiny, invisible water vapor. Now, here's where the magic happens! The steam builds up a lot of pressure inside the kernel because there's nowhere for it to escape.
Eventually, the pressure gets so high that the hard shell of the kernel can't hold it in anymore. That's when the kernel suddenly bursts open, and the pressure is released. When it bursts, it turns inside out and expands really quickly, creating that fun popping sound and turning into the fluffy, delicious popcorn you love to watch!
So, every time you see popcorn popping in the microwave, it's like a mini explosion happening inside each kernel because of the steam building up and bursting out. It's pretty cool, isn't it?
