Well I didn't know that, although the effect is inconsistent. What it does show is that water is strange stuff. Mpemba first noticed the effect in ice-cream, so I wonder if it still works if the water is de-ionized. You're right though I'll start a thread.
Originally posted by DeepThought I assume that you meant this the other way round:
...since hot water freezes faster than [water that is] cold or [at] room [temperature]
as I can assure you that a bucket of cold water will freeze more quickly than an otherwise identical bucket of boiling hot water if placed in freezing conditions.
Originally posted by Agerg Ok, noting that they cheated in that video by just throwing all the water away instead of leaving it in the cup to insta-turn cold, I imagine are you saying that we might not have to wait a whole hour. Perhaps it might only take a second or so before the step is taken that transforms it from being boiling hot to freezing cold. Even if that is so, if we divide ...[text shortened]... " mumbo jumbo please - again, as per your stance on evolution we don't accept changes over time.
They didn't cheat I told you in that post that if you took hot water outside
and threw it in the air that would happen. After I wrote post I thought I'd
try to find an example and did.

I thought it happen all the time, I remember reading that years ago did not
know it wasn't always true.

It's counter-intuitive, since one would expect the cold water to have a head start and therefore freeze first. The article JS357 linked to claims it is to do with hydrogen bonding, but the Wikipedia article gives several possible reasons, so I don't know that the matter is settled. An obvious control is to try it with some different substances and check that they don't exhibit the same effect. The story behind it, which is related in the Wikipedia article, is quite nice.

This could be seen as empowering "cults" who revel in being "few" and in declaring themselves to be "chosen". It also would appear to be at odds with the notion that one has only to believe ~ as billions do, and not "few" ~ to be saved, and that this salvation purportedly comes from that belief (alone) and not from being "chosen".
Well - this is why it is important to read in context and then think about it, not to quote single sentences and then fit them into a preconceived argument.

In my experience, the people who most often quote single sentences from Christian literature and then fit them into preconceived arguments and ideologies ~ especially on this forum ~ are Christians.
