Get your group in a circle with a nalgene brand water bottle (or any other object) in the center. Instruct the students that when you yell “Nalgene” (or whatever the object is) they are to look down at the object. When you yell “Face” they are to look up at someone else in the circle (but not someone directly next to them or the person they looked at the time before). If you are looking at the person who is looking at you then you scream as loud as possible and you are both out. The game continues for as many rounds as needed until there is only one person (or in the case of an odd-numbered group 2). I play this a lot with my jr high group and they all love it.
