A dozen slouching teenage boys shuffled into a makeshift classroom just off the juvenile block at the Philadelphia Industrial Correctional Center, one of the city's adult jails.
They were awkward and reticent at first as Jacob Winterstein, a poet, worked the room, challenging them with tongue twisters, icebreakers, moving to the beat playing from an iPod and a portable speaker. Two hours later, the teens were writing poetry and rapping - about street life and family, about the rhythm of the cell block and the fights that can disrupt it, about their regrets and hopes.
Winterstein was impressed.
"The best sessions," he said, "are where, by the end, we all kind of forget that we're inside of a jail."
