Cold out. Cold in as

Cold out. Cold in as well. But no snow here, either in or out, unlike much of the rest of south east England.
On the subject of cold things, there was an interesting discussion on the increasingly-irritating Today programme of the Mpemba effect. Essentially, as a result of the Mpemba effect, hot water will freeze over more quickly than cool water, even though that would seem to counter logic. Practical applications of this are that you should put cold water onto your pond or birdbath if you would like the creatures to benefit from that, and also use cold water to de-ice your car windscreen. (It should also be noted that hot water can shock your goldfish and delaminate your windscreen, and is therefore to be avoided).
