Sit on the floor in a circle. Someone (we suggest a leader) starts in the middle and says "The sun shines on people who (choose an attribute that more than one person, including the person saying it, in the room has, e.g. have blue eyes; are wearing red; have a sibling etc).
All the people who share that attribute must swap places and the person from the middle must try to take one of their places, leaving a new person in the middle to say the next "The sun shines on.." thing.
Continue until everyone is exhausted (or has had a go!). Similar to the "Have you ever" game
