One of my all time favourite films was shown on TV today. "Ice Princess" is a 2005 American figure-skating film directed by Tim Fywell and starring Michelle Trachtenberg, Joan Cusack, Kim Cattrall and Hayden Panettiere.
I'm not dreaming of becoming an ice princess, but like every country girl born and raised in a cold country, I love ice skating, especially on a lake. :)
With these collages, I participate in Mosaic Monday, one of my favourite link parties.
What I'm dreaming of is the crystal clear ice that makes it possible to skate everywhere on the lakes. I have experienced it only few times in my life. The ice is strong enough to carry a person and clear enough that you can see the water beneath, some aquatic plants and perhaps even fishes swimming around.
"On the surface of lakes, or other bodies of still freshwater, congelation ice is often called black ice. This ice has frozen without many air bubbles trapped inside, making it transparent. Its transparency reveals the colour, usually black, of the water beneath it, hence the name. This is in contrast to snow ice, sometimes called slush ice, which is formed when slush (water saturated snow) refreezes. Snow ice is white due to the presence of air bubbles.
Black ice grows downward from the bottom of the existing ice surface. The growth rate of the ice is proportional to the rate that heat is transferred from the water below the ice surface to the air above the ice surface. The total ice thickness can be approximated from Stefan's equation.
Black ice is very hard, strong and smooth, which makes it ideal for ice skating, skate sailing, ice yachting and some other ice sports. Thin, clear ice also has acoustic properties which are useful to tour skaters. Skating on clear ice radiates a tone whose frequency depends on the thickness of the ice."
