The World Food Prize Foundation this week will launch its Interactive Educational Exhibit Wing, which features more than a dozen exhibits with interactive displays, videos, photography and more that invite visitors to explore the world of food and agriculture, Iowa's humanitarian heritage, and global innovations in feeding the world. A special reception will be held Tuesday night from 5-7 p.m. for community leaders to preview the exhibits. The entire community is invited to explore the exhibits this weekend to the World Food Prize Hall of Laureates, 100 Locust St. All events are free of charge.
