This is a scientific explanation of the phenomenon of superheating in microwave ovens, published by The Hindu e-Paper on December 11, 2025. It explains that water can be heated above its boiling point in a microwave without visibly boiling due to its surface tension and the lack of nucleation sites. Adding anything to superheated water can trigger a sudden, explosive boil. The article advises caution and avoiding over-heating when microwaving water.

The Hindu e-Paper Warns: Microwave Users Beware of Superheated Water Explosions
December 11, 2025 – The Hindu e-Paper today published a cautionary piece explaining the dangers of superheating water in microwave ovens. The article, appearing in the “Question Corner” section, details the science behind the phenomenon, in which water heats above its normal boiling point without visibly boiling.
The article explains that water’s surface tension and the smooth surfaces of most microwavable containers prevent bubbles from forming, allowing the water to become superheated. Disturbing the water, such as by adding sugar or coffee, can then trigger a sudden and potentially explosive release of vapor.
“At normal air pressure, water boils at 100º C,” the article states. “However stable bubbles need extra energy to overcome surface tension, so water can be heated a few degrees above 100º C without properly boiling. This condition is called superheating.”
The Hindu e-Paper urges users to avoid over-heating water in microwaves and to exercise extreme caution when adding anything to heated water. The article serves as a timely reminder of a common household hazard.
