Throughout the twelve-hour-long extravaganza, visitors are invited to meet the curators, collections keepers, conservators, archivists, archaeologists, anthropologists, and researchers of the Penn Museum-and find out about their favorite artifacts or current research activities at the Museum and around the world. The day features conservators at work on Egyptian mummies and related artifacts at the "In the Artifact Lab" gallery project, educators offering interactive "cartifacts" exploring the Maya and ancient Egyptian and Mediterranean cultures, special "Reports from the Field" excavation talks by Kolb Junior Fellows, and behind-the-scenes tours of the Mainwaring Wing storage collections. In the evening, guests can experience the galleries in a distinctively different way, as Penn graduate students, counselors for the popular "40 Winks with the Sphinx" sleepover program, offer flashlight tours of the ancient Egyptian and Mediterranean galleries.
