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.
Just as with snow, the farther the light travels into the ice, the more red is absorbed and the bluer the ice gets. Blue ice means thick, safe and strong ice â a good thing to know when crossing a frozen sea. So, why were last weekend's snowbanks so brilliantly blue? This was a heavy, wet, dense snow with as much as five times the weight of dry snow. Wet snow will, because there is more of it in a given area, absorb a lot more red light than dry snow.
