Univ. professor makes 'popped snack' at campus

MATSUYAMA, Japan - Toshihiro Wada, professor of business history at Ehime University, makes "pon-gashi" (literally "popped snack") from rice grains using a portable high-pressure cauldron at the university campus in Matsuyama, Ehime Prefecture, western Japan, as seen in this file photo of July 2014. The machine was invented by an old woman who sought to produce easy-to-make, stomach-friendly "pon-gashi" from rice and other grains to feed children amid food shortages in Japan during World War II.
