Looking at my coffee this
morning, I noticed a bubble on the surface.
It was a small bubble, and I began to wonder if the temperature inside
that bubble was as hot as the liquid coffee it was floating on.
In thinking about that, I
considered for a moment that I was standing inside that bubble. The air surrounding me would be very warm
and breathing it in would surely be uncomfortable. I know breathing in the cold air of winter
does not feel all that good, so it makes sense hot air would be just as bad.
This brief mental excursion was
cut short as soon as I pictured my shoes standing on the surface of the
coffee. Obviously, my weight would be
enough to cause the coffee to flow up over the sides of my shoes, causing me to
slowly sink, like some canoe attempting to support one too many.
