One article, titled “Question Corner/Physics,” answers the question of how a candle wick holds a flame for so long. The answer explains that the wick draws liquid wax upwards through capillary action, which then vaporizes and burns. The wick is designed to burn itself slowly, curling into the flame to self-trim and prevent smoke.

The Hindu Explains the Science Behind Candle Flames

NEW DELHI – November 26, 2025 – The Hindu’s e-Paper today delves into the surprisingly intricate science behind a simple candle flame. In the “Question Corner/Physics” section, the publication addresses a query from a reader, Sadhika G., asking how a candle wick manages to sustain a flame for extended periods.

The answer reveals that the burning process isn’t simply about the wick itself. Rather, the wick acts as a delivery system, using capillary action to draw melted wax upwards. This liquid wax then vaporizes near the flame, and it’s the wax vapor, not the solid or liquid wax, that actually fuels the combustion.

Furthermore, the article explains that well-designed wicks are engineered to curl over as they burn. This curling action positions the wick’s tip in the hottest part of the flame, allowing excess material to turn to ash and break off. This self-trimming mechanism prevents excessive smoke production and ensures a steady, long-lasting flame.

The Hindu’s science feature offers a clear and accessible explanation of a common phenomenon, highlighting the publication’s commitment to making scientific principles understandable for its readers. This article joins a diverse range of content in today’s e-Paper, including analysis of global affairs from an Indian perspective, reviews of the latest films and streaming releases, technology updates, and health and wellness advice.
