Sink or swim Form two teams. Left side versus right side. Line up in two lines across the room facing each other. I will ask someone on team 1 a question, if they get it right they may “sink” someone on team 2. (this person must sit down) I will then go to someone on team 2, if they answer their question right they may either “sink” someone on team 1 or rescue their "sunken" team member. The winning team is the team with the most people still standing.
