Did you know that ancient Indians could manufacture ice during warm nights without a single machine? 🤯
In 1775, a British officer named Sir Robert Barker witnessed something in Allahabad that seemed to defy the laws of nature: Indians making ice in the middle of a 41°F summer night!
How did they do it? By placing shallow ceramic pans of water on beds of straw in open fields, they utilized a brilliant scientific principle called “Radiative Cooling”. The water sent its heat out into the cold, dark night sky, while the straw insulated it from the warm ground. By morning, the pans were completely filled with ice.
This ancient mastery of thermodynamics provided refrigeration to Indian cities thousands of years before the first mechanical compressor was ever built!
