*This fact seems counterintuitive, but it’s called the Mpemba effect, after a Tanzanian student named Erasto Mpemba who told his teacher than a hot mixture of ice cream froze faster than a cold one. Scientists now believe this is because the velocities of water particles have a specific disposition while they’re hot that allows them to freeze more readily. If proven correct, this finding could also have implications in daily life, like cooling down electronic devices.
*Cold water heats up faster than hot water.
*Humans are related to fungi.
