Sponge? Styrofoam?

Now I know what you're probably thinking: it's white styrofoam taken up close!
Though it is a good guess, it is an incorrect answer.

Popcorn!

When popcorn is microwaved into a delicious snack, it turns out the outer white layer is quite similar in structure to the polystyrene foam we see in many places throughout our lives!
Popcorn actually has a small amount of water inside the hull. When it is microwaved, the water evaporates, causing pressure to rise and ultimately exploding the popcorn - thus creating the famous food for movies.
