History
The oldest puffed grain was found in west central New Mexico in 1948 and 1950. Ears of popcorn were found that were up to 4,000 years old. These pieces of puffed grain were smaller than a penny to two inches in size and can be made in a similar way to popping popcorn. The modern process of making puffed grains was invented by Dr. Alexander P. Anderson in 1901. He was doing an experiment dealing with the effect of heat and pressure on corn starch granules where he put them in six glass tubes, sealed them, and put them in an oven until they changed color. When Dr. Anderson took them out and cracked them open an explosion happened, he had made the corn starch turn into a puffed, white mass. Dr. Alexander’s invention of puffed grain was first introduced at the World’s Fair in St. Louis in 1904. The puffed grain was shot from a battery of eight guns and on a poster it was called “The Eighth Wonder of the World.”

Famous quotes containing the word history:
“The history of all previous societies has been the history of class struggles.”
—Karl Marx (1818–1883)
“No one is ahead of his time, it is only that the particular variety of creating his time is the one that his contemporaries who are also creating their own time refuse to accept.... For a very long time everybody refuses and then almost without a pause almost everybody accepts. In the history of the refused in the arts and literature the rapidity of the change is always startling.”
—Gertrude Stein (1874–1946)
“It would be naive to think that peace and justice can be achieved easily. No set of rules or study of history will automatically resolve the problems.... However, with faith and perseverance,... complex problems in the past have been resolved in our search for justice and peace. They can be resolved in the future, provided, of course, that we can think of five new ways to measure the height of a tall building by using a barometer.”
—Jimmy Carter (James Earl Carter, Jr.)
