Mpemba effect Explained
The Mpemba effect is the observation that very hot liquids can freeze faster than colder ones. Dessert physics is just regular physics with sugar. In 1963, Erasto Mpemba noticed his hot ice cream mixture froze before a cold one.

In 1963, Erasto Mpemba noticed his hot ice cream mixture froze before a cold one. A teenager outsmarted dessert.
He asked why water at 100 degrees Celsius freezes before water at 35 degrees Celsius. Osborne confirmed it.
They placed 70 ml water samples in 100 ml beakers on polystyrene foam inside a refrigerator. Domestic fridges harbor deep physics.
Boiling water beat room temperature in a freezer.
Ancient scientists noticed this too. Aristotle wrote that previously warmed water cools sooner because of antiperistasis.
Modern physicists remain divided on the precise definition and underlying mechanisms. In 2016, reviewers found no evidence.
The effect has since been studied in magnetic alloys, nanomechanical systems, and quantum systems. Hot ice cream started everything.
