   If you breathe on a cold window, you can sometimes see the moisture
   freeze before your eyes, often forming shapes similar to snowflakes.
   These breath crystals are frozen directly from the air, forming the
   delicate leaves shown above, some of which are as long as 5 cm (2 in).
   To see breath crystals like these, the air temperature needs to be
   below about 14 F (-10 C).
