The Science Behind Floating Diyas in an Urli

While the act of lighting an earthen lamp (diya) is primarily associated with cultural and spiritual practices, there are a few scientific reasons why it can be beneficial-

Traditional earthen lamps are typically fueled by oils such as sesame oil or ghee. When burned, these oils release low levels of particulate matter and pollutants compared to other indoor lighting sources, such as candles or incense sticks. Lighting an earthen lamp can help minimise indoor air pollution and improve the air quality within a confined space.

An earthen lamp's flame produces heat, creating a natural updraft of air. This updraft helps in circulating and purifying the air around the light. It can contribute to better air circulation, especially in enclosed areas, potentially reducing stagnant air and promoting a fresher environment.

The visual warmth of the flame can create a cosy and comforting atmosphere, which may positively impact one's mood and psychological well-being.

Lighting and tending to an earthen lamp can be a mindful practice. It can serve as a focal point, promoting a sense of calm and relaxation. Engaging in such mindful activities has reduced stress and increased overall well-being.

How do Diyas Float in the urli?

Here are some of the top factors that contribute to the floating of diyas in an urli -

Buoyancy- It is the upward force exerted by a fluid (in this case, water) on an object immersed or floating. The principle of buoyancy states that the upward pressure is equal to the weight of the displaced fluid. When a diya is placed in an urli filled with water, it displaces an amount equal to its weight. If the importance of the diya is less than the weight of the water it displaces, it will float.

Shape and design- The design of the diya plays a crucial role in its ability to float. Traditional diyas used for floating are usually made of clay or similar materials, which are lightweight and have an open or concave design. The concave shape allows the diya to hold oil or ghee (clarified butter) and a wick while contributing to buoyancy. The air trapped inside the diya adds to its buoyant force, helping it float on the water's surface.

Surface tension- Surface tension is the cohesive force between liquid molecules at the surface of a liquid. In the case of water, surface tension allows it to form a "skin" or "film" on its surface. When a diya is placed gently on the water's surface, the surface tension helps distribute the weight of the diya, preventing it from immediately sinking. This phenomenon allows the diya to float until the surface tension is disrupted.
