It sounds impossible, but hot water can actually freeze faster than cold water — a strange phenomenon called the Mpemba Effect. At around -40°C, when both hot and cold water are exposed, the hot water turns to ice first. Scientists still debate the exact reason, but it’s linked to evaporation, convection, and molecular structure. Hot water loses mass faster through steam, and the molecules move in a way that helps them lock into ice crystals sooner. This effect was first noticed by a Tanzanian s
