How Popcorn Pops Some flint and dent
varieties of corn will explode and form a crisp
puff, but expand far less than true popping
varieties, which are generally smaller and
contain a greater proportion of hard
translucent endosperm. Thanks to a denser
arrangement of cellulose fibers, the popcorn
hull (pericarp) conducts heat several times
faster than the hull of ordinary corn; and
thanks to both its density and greater
thickness, it is several times stronger: so the
hull transmits heat more rapidly to the
endosperm, and can withstand higher steam
pressure from within before giving way.
