DURING THE TIME UP TO SATS EXAMS THERE WAS A QUESTION ABOUT GLOBAL WARMING AND MELTING ICE CAPS.  IT SAID THAT AS THE CAPS SHRINK LEVELS WILL RISE BUT, I SAW IT AND THOUGHT FOR A BIT. ACCORDING TO ARCHIMEDES, THE LEVEL WOULD STAY THE SAME. THE CAPS WOULD MELT BUT, BECAUSE THEM MELTING WOULD RESULT IN LEVELS STAYING THE SAME WOULDN'T IT?  I TRIED THIS WITH A GLASS OF WATER AND AN ICE CUBE AND THE WATER DID NOT RISE. DOES ANYONE HAVE AN EXPLINATION OR IS IT JUST TOTAL RUBBISH?                                                                                                                                                                                                  Felix, 12 From Norwich
