This site from the Exploratorium provides an activity to detect the flickering of a LED or neon glow tube. These light sources turn on and off too frequently to be observed normally, but when an observer makes a raspberry (gives a Bronx cheer), the observer sees a flickering light. The site contains an explanation for the effect and suggestions for other activities that demonstrate the same results. This activity is part of Exploratorium's Science Snacks series.
