lucky git!
my physic teacher was a religious nutcase.
he spent 4 years trying convince us that god exists!!!
and his proof???
everything contracts as it gets colder , except water which starts expanding at 4 degree's
this means ice floats and top layers of water freeze first protecting water underneath.
his arguement is
if this didnt happen, water would freeze from bottom up, killing all life in the sea during iceage.
quite an unusual approach from a physics teacher....
