Ever heard of Mpemba effect?
It was first observed by Aristotle in the 4th century BC, then later by Francis Bacon and René Descartes, but the effect was named after the Tanzanian student whom in 1963 noticed that hot ice cream mix freezes faster than a cold one.
And if you are asking yourself if hot water freezes faster than cold water, the answer is YES! This phenomenon surprised not only us, but even scientists and that is why most readers may be extremely skeptical about this fact.
In this article written in 1998 Monwhea Jeng from the Department of Physics in University of California it is well explained how this weird phenomena occurs.
