Physicist Helen Czerski from BBC Earth transforms sound into a visual marvel using ordinary tea candles and a giant speaker. As the loud sound waves pulse through the air, the flickering flames paint a mesmerizing dance, moving in flawless synchrony with the beats. This captivating experiment reveals the hidden patterns of sound waves in an unexpected and illuminating way.
The science behind the flicker
Helen Czerski demonstrates a striking method to make sound waves visible. By placing small candles in front of the speaker, the vibrations cause the flames to flicker in time with the sound. This simple yet effective setup visualizes the rhythm and intensity of the waves, offering a tangible way to appreciate the complexity of sounds we often take for granted.
