The Ganesha Milk "Miracle" of 1995
The phenomenon of idols apparently drinking milk gained international attention on September 21, 1995. Starting with an offering to a statue of Lord Ganesha in a temple in New Delhi, the news spread rapidly through telephone calls and word-of-mouth. Soon, similar occurrences were reported across India and in Hindu temples around the world, from the UK to the US. Millions of devotees flocked to temples, offering milk to statues and witnessing the liquid seemingly disappear, leading to mass hysteria. The event caused a temporary spike in milk sales and major traffic congestion around temples. For many, it was a profound sign of divine intervention and a powerful affirmation of faith. However, for scientists and rationalist groups, it represented a clear example of a natural phenomenon being misinterpreted.
The Scientific Explanation: Capillary Action and Surface Tension
The widely accepted scientific explanation for the "miracle" is a combination of two basic physics principles: capillary action and surface tension. While the effect may seem magical, it is a routine interaction between liquid molecules and a solid surface.
The Role of Capillary Action
Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of external forces, or even in opposition to them, like gravity. This is the same principle that allows a paper towel to soak up a spill or a plant's roots to draw water upwards. It is a result of intermolecular forces working together. For the idol phenomenon, the key factors are:
- Adhesion: The attractive force between the milk molecules and the molecules of the idol's surface. Many statues are made of porous materials like stone or ceramic, which are filled with tiny, interconnected gaps.
- Cohesion: The attractive force between the milk molecules themselves. This force holds the liquid together.
- Surface Tension: The cohesive forces between liquid molecules at the surface create a film-like effect. This tension allows the liquid to cling to a surface.
When a spoonful of milk is brought into contact with the porous surface of the idol, the forces of adhesion between the milk and the stone become stronger than the cohesive forces within the milk. The liquid is then drawn into the statue's narrow pores, and the surface tension helps pull it up and out of the spoon.
The Influence of Surface Tension
Surface tension plays a critical role in the initial transfer of milk from the spoon to the idol. When a spoonful of milk is tilted towards the statue, surface tension causes the milk to cling to the spoon. When the spoon touches the idol, the adhesive forces from the idol's surface disrupt the milk's surface tension, causing the liquid to spill out onto the statue rather than drip naturally. From there, capillary action takes over, drawing the milk into the porous surface.
How Scientists Replicated the Phenomenon
To prove the scientific basis of the event, Indian scientists and rationalist groups performed public demonstrations. A team from India's Ministry of Science and Technology, for instance, visited a temple and offered milk mixed with a colored food dye. They observed the liquid disappearing from the spoon, but the colored dye coated the idol's surface and flowed down unseen channels, proving it was simply being absorbed rather than consumed. Similar experiments conducted with regular statues or even other porous materials showed the exact same effect, further confirming the physics at play.
What Happens to the Milk?
So, where does all the milk go? The liquid disappears from the spoon but doesn't vanish. The fate of the milk depends on the specific idol and its environment:
- Absorption and Drying: The milk is absorbed into the porous material of the statue, much like a sponge absorbs water. Over time, the moisture evaporates, leaving behind a residue of milk fats, proteins, and sugars.
- Hidden Drainage: In some cases, the milk is drawn into crevices and unseen channels, eventually draining into the pedestal or being absorbed by offerings of flowers and fabrics placed at the idol's feet.
- Saturation: The "miracle" was short-lived because, once the idols became saturated with milk, they could no longer absorb more, and the effect ceased. This is a clear indicator that the process was finite and physical, not an act of endless consumption.
Comparison: Science vs. Folklore
To understand the opposing viewpoints, a comparison of the scientific and folklore interpretations of the event is useful.
| Feature | Scientific Explanation | Folklore/Mythical Interpretation |
|---|---|---|
| Mechanism | Capillary action and surface tension, governed by physics. | A divine miracle or supernatural event. |
| Idol's Nature | A statue made of porous materials like stone or ceramic. | A living or animated representation of a deity. |
| Observation | The milk is drawn from the spoon, coats the idol, and is absorbed or drains away invisibly. | The idol is believed to be consuming the milk as a blessing. |
| Durability | The effect stops once the idol's surface is saturated with liquid. | The miracle is a one-time, brief divine sign, not a sustainable process. |
| Replicability | The effect can be easily replicated in a laboratory setting. | Cannot be recreated through human means, only happens through divine will. |
Conclusion: Separating Myth from Physics
While the sight of a statue seemingly drinking milk can be a powerful emotional experience for believers, the scientific community has provided a clear, verifiable explanation based on fundamental physics principles. The Ganesha milk miracle of 1995, though remarkable in its spread and impact, is a textbook example of capillary action and surface tension in action. It highlights how natural phenomena can be misinterpreted as supernatural events, especially in times of collective excitement and strong belief. Ultimately, understanding the science behind idols drinking milk allows for a deeper appreciation of the physics that governs the world around us, while also acknowledging the powerful human element of faith and interpretation.
Exploring Capillary Action in Everyday Life
The principles behind the milk phenomenon are not confined to temples. Capillary action is all around us, often going unnoticed. Common examples include:
- Paper Towels: The fibers in a paper towel are like tiny tubes that pull water upwards.
- Plant Life: Plants use capillary action to transport water from their roots to their leaves through xylem tissues.
- Wicks: An oil lamp wick draws fuel upward to the flame via capillary action.
Understanding these everyday applications demonstrates that the forces at play in the 1995 event are a regular part of our physical world.

The Psychology of Mass Hysteria
Beyond the physical science, the Ganesha milk miracle also provides insight into social psychology and mass behavior. The rapid spread of the rumor via telephone and word-of-mouth created a feedback loop where people's beliefs were amplified by others' apparent confirmation. This demonstrates how collective emotional states can influence perception, leading people to see what they expect to see, a phenomenon known as confirmation bias. The event serves as a classic case study in how belief, even when based on misinterpretation, can spread and become a powerful cultural force.
Conclusion
In conclusion, the science behind idols drinking milk is firmly rooted in the laws of physics, particularly capillary action and surface tension. While the 1995 event captured the world's attention as a potential miracle, scientific inquiry and replicable experiments confirmed it was a natural process. Porous stone idols, combined with the cohesive properties of milk, created a visual illusion of consumption. This famous incident serves as a powerful reminder of the intersection between human belief and the verifiable physical world, demonstrating how easily natural phenomena can be perceived as supernatural.
