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.
1: Icebergs turn blue because of pressure that compacts the ice and dislodges the air trapped inside. Wrong, in fact the hollow areas with the most air (crevices and holes) are the bluest. 2. Old Icebergs are blue, young ones are not. Wrong. Often times ancient Icebergs are white and very young ones are deep blue. 3. Icebergs are blue because of refraction. Wrong. For those of you who do not remember what refraction is, think of what happens when you submerge part of a straight object like a pencil in water. The object appears to bend at the surface. There is some refraction in glaciers, but its effect is negligible.
