“One Christmas when I was a kid, we took a family vacation to Vancouver. It was the first time I saw snow. When my dad explained to me that it was below freezing outside, I asked him, "Does that mean if I leave ice cubes outside, they won't melt?" "You can try," he replied.

So I took some ice cubes and left them outside our hotel room, and sure enough, the following morning, they were still there, intact. That was a true surprise for a kid growing up in Hawaii.”
