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.
Why are glaciers blue? Small ice pieces, as well as snow, looks white, because the sunlight shining onto them gets completely reflected back, and no absorption of light by the ice particles take place. Hence, small ice pieces and snow appear white. However, large ice bergs and glaciers in most places appear blue in color. In nature, there are other things that appear blue, like the sky and sea water. But the phenomena involved in both cases that makes them appear blue are different, although they result in the same blue color.
