but there is a serious message to be had here.
Qustion... What % does water expand to when frozen?
No prize for the winner

[Crystal-clear]

water expands when frozen to 10%-15% i think.

[bad trippy]

Come on you lot, you work with it everyday, you surely must know the answer

Well done go to the top of the class, 10% is the correct answer

[bad trippy]

And the first thing that will blow is the weakest part, ie a join or fitting

Does that mean when the polar ice caps melt instead of all the dreaded flooding there will be 10% less ocean

And at what temperature is water at its most dense?

Vin

3.98 degrees Celsius

           Nope

3.98 degrees Celsius

It's almost as if you looked it up...

Nope I knew the answer hounest guv

Stu Mac, I hope you didn't look on Wikipedia - very unreliable.

My guess would have been what is known as absolute zero.  I think that about -200 or -300 (can't recall exactly).  Indeed I reckon it must be theoretical anyway.

The third form physics is if you draw a graph of volume against temperature where things get smaller or contract as they get colder- and it turns out its a straight line- and this straight line if you follow it on crosses the x axis for zero volume at -273 celcius.

So absolute zero is that cold that there is no volume at all. That's pretty cold.

Ah, but only for gases.

And this is fun...

You forgot the question mark after fun, Vin.
