We all get the Mpemba effect is totally fake right? You all own freezers so you can test it for yourself, it was found by a child making icecream so it will be easy! And if you're the !first! to put it on Youtube that'd be cool. Sciencium talks about it here if you want an ok run down and how it's not real - [VIDEO]

There was a video by Derek/Veritasium as few years ago explaining this and also walking through all the experiments that demonstrate the effect does not in fact exist. [VIDEO]

It's because you was wrong (or at least not correct). The Mpemba Effect wasn't scientifically proven, and can be explained away with error in measurement. [VIDEO]
