Anybody have some ideas for a 5 minute children's time at church?

Members of our Baptist congregation take turns doing a 5 minute "children's church" during our worship service on Sundays. One time before, I had a child attempt to pick up a hymnal with ONE finger. Obviously, it couldn't be done. But he could pick it up with ALL of his fingers. This signified how the church works together and that each person is important...we can't do it on our own. Well, I'm supposed to do Children's Time again this Sunday and am looking for fresh ideas. Thanks in advance!
