In a big hall place cuttings out of magazines each side of the wall. For example you could have shoes, jackets, cd players, computers on each side. Split the youth group into two groups. The youth leader then calls out one of the items. The first person in each group has to run up get the picture of that item, touch the wall at the other end and come back with it. The first person to come back with the correct item scores a point for their team. The team with the most points at the end wins.
