It seems unnatural, but the laws of physics don't lie. Liquids require heat to boil, and if the conditions are right one liquid can be boiled in order to freeze a second. Under a vacuum, the water in an acetone/water mixure can freeze while the acetone boils.

Dr. Carlson,
My daughter and I like your green hair. She would like to know if you dyed it due to a lost bet or if it was for St. Patrick's day.
Ah, my green hair sometimes comes around St. Patrick's day, but is primarily done to celebrate spring.
I like color in general, and green is my favorite, so I occasionally dye my hair a wild color just for fun.
Oh, and I forgot to mention. I decided I "earned the right" to dye my hair any color I wanted once I recieved my PhD. :)
