Hot Water Freezes Either Faster or Slower Than Cold Water

Описание: The Mpemba Effect happens when hot water freezes quicker than room temperature water, or does it? Alex goes on an exhaustive journey to replicate the Mpemba effect and hits a few snags on the way, including a paper being released the week this video was supposed to come out. Does this paper finally resolve all existing ambiguities about measuring relaxation speeds in the Mpemba Effect? Well, it claims to.
