In this activity, learners observe what happens when they give a light source like a neon glow lamp a "Bronx Cheer." The lights appear to wiggle back and forth and flicker when learners blow air through their lips. However, learners will discover that the only thing vibrating is themselves. Use this activity to explore different forms of light as well as visual perception.
