Popcorn, or pop corn, is a variety of corn kernel, which forcefully expands and puffs up when heated.

A popcorn kernel’s strong hull contains the seed’s hard, starchy endosperm with 14-20% moisture, which turns to steam as the kernel is heated.

The pressure continues building until it exceeds the hull’s ability to contain it.

The kernel ruptures and forcefully expands, allowing the contents to expand, cool, and finally set in a popcorn puff 20 to 50 times the size of the original kernel. (source)

Can guinea pigs eat popcorn?

They can eat plain popcorn, but not salted, flavored or sweet popcorn.

Plain popcorn is fine for them to nibble on but it provides no nutritional value for them.

It should be considered as a treat for them to have every so often.
