oK SO this has always been bugging me... I can remember doing a science experiment in high school to test how fast water can freeze. we did boiling water, room temp water and ice cold water. I can remember that hot water froze the fastest as the temp gradient plumeted the fastest? am i not remembering this correctly? makes me want to do another test.

Your right man , I take room temperature out when I need . Poured in pail in house night before .

That's what I do too! Weekdays anyway, because I don't have time to heat the filtered well water in the waterer before taking it out in the mornings. I didn't really know the science behind it. Good to know I inadvertently did the right thing.
Why filtered well water, you ask? Because our water that bypasses the the water softener and before the Brita filter tastes "not nice". At all. So I run it through a Brita before filling the waterers.

HAHAHA now that was cool! since I kinda hijacked Brians thread i decided to try and split the thread and create my own... Success!

What he says lololol

it is a fact jack! its called the Mpemba effect.

You are right hot water freezes fastest, I use the water straight from the well except the chicks always get warm water.

Hot water has less air in it to buffer the cooling so it cools faster than water with air in it. Its patly because when water freezes it has to form crystals. No air = large straight crystals grow faster. In air saturated water the crystals sre forced to be short because of the air they cant grow as fast and have to have more nucleation sites. Also...if you want nice foggy white ice cubes use cold tap water. You want crystal clear ice cubes use boiling water from a kettle after it has boiled for a minute. Dont melt your plastic tray tho....

Thanks for the in depth explanation Kathy, when you put it like that it makes sense! so why do a lot of people give warm water to their birds? it cant be to try to keep it from freezing... hmmm

When you guys say, "warm".... how warm are we talking? My cold from the tap could be fresh out of the cistern cold or basically room temp if the pump hasn't come on for a while. Is there a best temp?
