Science Explained What will freeze first, hot water or cold water? March 12, 2026 by Tanp | Leave a Comment The common misconception that hot water freezes faster than cold water is counterintuitive but true under specific conditions, a phenomenon known as the Mpemba effect. While cold water generally freezes faster due to its lower initial temperature, certain factors can cause hot water to reach the freezing point and solidify more quickly. Unpacking the Mpemba […] Read more »
Science Explained Does sugar keep water from freezing? March 11, 2026 by Tanp | Leave a Comment Sugar does not prevent water from freezing; in fact, it lowers the freezing point of water. Adding sugar to water creates a solution where the sugar molecules interfere with the formation of ice crystals, meaning it will freeze at a lower temperature than pure water. This principle is utilized in various applications, from making ice […] Read more »
Science Explained Will adding salt to water keep it from freezing? March 11, 2026 by Tanp | Leave a Comment Adding salt to water does lower its freezing point, meaning it will stay liquid at temperatures below 0°C (32°F). This is why salt is often used to de-ice roads and why saltwater freezes at a lower temperature than pure water. The amount of salt added directly impacts how much the freezing point is reduced. Understanding […] Read more »
Science Explained Does rubbing alcohol melt ice in the freezer? March 9, 2026 by Tanp | Leave a Comment Rubbing alcohol does not melt ice in a freezer; instead, it lowers the freezing point of water, preventing it from freezing solid. When added to water, rubbing alcohol creates a solution that requires a much colder temperature to freeze than pure water. This principle is why rubbing alcohol is used in de-icing solutions for cars […] Read more »
Science Explained Does a ping pong ball stop water freezing? March 1, 2026 by Tanp | Leave a Comment A ping pong ball will not stop water from freezing. While a ping pong ball might offer a slight, temporary insulation effect on the surface of the water, it lacks the mass and insulating properties necessary to prevent the entire body of water from reaching its freezing point. Factors like ambient temperature, water volume, and […] Read more »
