Matthew extinguishes a flame with sound waves

Today Matthew used sound waves to oscillate air. The air then blew out a candle. He had an empty plastic juice bottle which he cut the bottom off. He made this bottom end into a drum by stretching glad wrap over it. Then when the drum was sounded quite a distance from the flame, the flame was extinguished. Everyone left their own work to watch him repeat it several times.
