ABSTRACT

In this entry, we present the data obtained on the 8th September 2005, 1pm. The results demonstrate the Mpemba effect to be complete bollocks under the conditions of a home kitchen.

METHOD AND EQUIPMENT

Two coffee cups from the Filterfresh coffee machine were used. They were filled with 250ml of water from a Poland Springs dispenser.

Cup A was filled with water from the hot tap at 65 Deg C, while Cup B was filled with water from cold tap at 7 Deg C.

The two cups were placed in the freezer and the temperature monitored periodically.

RESULTS

The author was bored and had to get to class at this point, so the experiment was cut short. We did return an hour later to find Cup B to be completely frozen while Cup A was still only ¼ frozen.

DISCUSSION

Clearly the Mpemba effect is a load of crap in this case. Note it might still be possible to make hot water freeze before the cold (like in the case of water thrown into the cold air as stated by Prof. Black Mamba*), but the author feels that his conditions and materials are representative of a standard kitchen/cooking environment.

CONCLUSION

The verdict is clear.

* The Black Mamba was taken captive by the barbarian hordes together with me. He escaped from the Institute about a year ago. He has been wanted ever since for committing countless indecent acts and is considered extremely lecherous.
