They can sink and drown if the water is too deep or if. they get overly tired. Do not allow them to get chilled or get excessively wet before they are feathered out. They can. get chilled even in wet grass. I recommend using shallow pans to let them splash around in.
Walter White's discards, commented one Facebook user, comparing the turquoise ice to the blue meth Walter White cooks up in Breaking Bad. Unlike Walter White's creations, the blue ice on Lake Michigan has much less illicit origins. The bizarre coloring has to do with the ice's density. Ice only appears blue when it is sufficiently consolidated that bubbles do not interfere with the passage of light, explains this Carleton University guide to glaciers.
A large piece of compressed ice, or a glacier, would appear blue as large quantities of water appear blue. The latter is because the water molecule absorbs other colors more efficiently than blue. The other reason for the blue color of glaciers is the lack of air bubbles.ong, sinuous glacial deposits are called eskers. Eskers are composed of sand and gravel that was deposited by meltwater streams that flowed through ice tunnels within or beneath a glacier. They remain after the ice melts, with heights exceeding 100 meters and lengths of as long as 100 km.
