Schoolchildren from the Geza Gardonyi Primary School in Devecser, Hungary view part of an exhibition dedicated to the industrial accident that ruined many of their homes and which features their original artwork of children's messages for the children of their village and a neighboring village, Kolontar, at the Hungarian National Museum in Budapest, Hungary on November 26, 2010. On October 4, 2010, a ruptured industrial reservoir sent a torrent of toxic red alumina sludge gushing through their village, Devecser, and several surrounding villages, killing ten, injuring hundreds, and leaving several families homeless.
