Players walk around the room and name objects they see, touching them as they do: 'Wall.' 'Corner.' 'Heater.' Continue for one to two minutes.
Then repeat the exercise, but this time name everything wrong. Touch a chair and say 'Applesauce.' Touch the floor and say 'Handbag.' Touch the window and say 'Elephant.'
Advanced variant: In a third round, name each object with the previous wrong name you gave to a different object. This is extremely challenging and trains quick thinking and spontaneity.
