Nose Basher (swinging bowling ball)

Hang the bowling ball from the ceiling hook in the lecture hall. Pull the ball back to the side and place against the nose of the student. Give them the ball to hold. At the signal have them "let go" of the ball and stand very still. The ball will swing back "near" the person's nose but never hit it due to friction. (Don't throw the ball.)
