If you're feeling chilly, think about the people sleeping tonight in the Ice Hotel. Built every winter in Quebec, Canada, the Ice Hotel really is a sparkling hotel totally made of ice and snow. The smooth, almost-clear blocks of ice gleam a faint blue, and are held together with 15,000 tons of packed snow. Even your bed is a block of ice with a deerskin over it (we've slept on it). And it's less than 30 degrees F inside the hotel, since of course there's no heat!
