Popcorn History
http://www.ht-express.com/howto-history-popcorn.htm Popcorn was essential to 16th century Aztec Indian ceremonies, which Bernardino de Sahagun writes, “And also a number of young women danced, having so vowed, a popcorn dance. As thick as tassels of maize were their popcorn garlands. And these they placed upon (the girls’) heads.” The Aztec Indians used popcorn as a decoration for ceremonial headdresses, necklaces, and ornaments on statues of their gods, including Tlaloc, the god of rain and fertility.
