The Mpemba effect is the name given to the observation that a liquid (typically water) that is initially hot can freeze faster than the same liquid which begins cold, under otherwise similar conditions. There is disagreement about its theoretical basis and the parameters required to produce the effect.
Pumpable ice flows like water, and because it is homogeneous, it cools fish faster than freshwater solid ice methods and eliminates freeze burns. It complies with HACCP and ISO food safety and public health standards, and uses less energy than conventional freshwater solid ice technologies. [8] [9]

During the final stage of freezing, an ice drop develops a pointy tip, which is not observed for most other liquids, and arises because water expands as it freezes. [10] Once the liquid is completely frozen, the sharp tip of the drop attracts water vapor in the air, much like a sharp metal lightning rod attracts electrical charges . [ 10 ]
When water freezes, most impurities are excluded from the water crystals; even ice from seawater is relatively fresh compared to the seawater from which it is formed. As a result of forcing the impurities out (such as salt and other ions) sea ice is very porous and spongelike, quite different from the solid ice produced when fresh water freezes.

Iguanas go into this cold-stunned state as a way of protecting themselves until the temperature warms back up above 50 degrees. Magill said cold weather effects on iguanas depends on the size of ...
But in cold weather, the water sandwiched inside the soap has a chance to freeze before the bubble pops. As soon as you touch them, however, the heat from your fingers will melt the bubble.
