Hi scientist, In Holland, it is a tradition to organize every year a big ice-skate contest; the 'eleven-city-tour'. This 200 km. tour has, however, only been organized for a couple of times this century because the ice simply was too thin to allow 30.000 people to skate on it. This year, people have tried to do 'ice-surgery' by adding ice-blocks on places with just water. This works fine. On other places, the ice is too thin. Now here's the question. I think that the ice would grow faster when water is put on TOP of the ice, instead of waiting for the ice to grow. The reason would be that ice does not transport heat from down to up as fast as water does from up to down (water feels colder than ice, so i think it transports heat and cold faster and the cold must come from the outside-air. Besides that, warm water goes up, so for the ice to grow at the bottom, first about 2 meters of water has to be cooled to almost zero degree celsius. I've got a bet on it, so please answer me that i'm right (it would also be a revolution in holland ;-)). Thanks in advance, Joep B.T.W. This web-page really is a great idea!
