10/31/11 Dry ice

Dry ice fogs up I think is because dry ice is ice frozen for a very long time and then when water pours over it the little wamth of the water makes it fog up. what really happens is that they make ice with only carbon dioxide and water and then when it heats up to like -88 it makes smoke. freezing (from liquid to solid) boiling (from liquid to gas) melting (from solid to liquid) sublimination (from gas to liquid) condencing (from solid to gas).
