Collect together a number of objects and place in a canvas bag. The objects can include everyday items i.e. a pencil, key-ring, mobile phone, but also include some more unusual ones i.e. a fossil, holiday photograph, wig! Pass the bag around the group and invite each young person to dip their hand into the bag (without looking) and pull out one of the objects. The leader begins a story which includes his object. After 20 seconds, the next person takes up the story and adds another 20 seconds, incorporating the object they are holding. And so on, until everyone has made a contribution to your epic literary tale.
