Center Point Urbana students Christie Meyer, 14 and Kearstin Woods, 13, pick out a playtlist of music to work to on top on a pile of water bottles that would later become part of their creation Saturday morning at the Coral Ridge Mall. Architects, engineers, local students, and youth groups built structures Saturday morning out of cans to be donated to the HACP Food Reservoir and be distributed to Linn and Johnson County food pantries and crisis centers. The teams had from 8 until 11 AM to assemble their constructions at the Coral Ridge Mall and were judged on their creations.
