A Cool Coca-Cola Zero Can

Room temperature

Cold can

I have a few regular Coca-Cola cans that have printing that changes color in different temperatures, but this is my first Coca-Cola Zero can with that printing.  The label says when the white turns blue it's ready to enjoy.

The other cans I have just have the image of a soda bottle that changes color (which this one also has), but what's neat about this one is the letters C-O and O-L also turn blue, spelling out the word "cool."

Now that is cool!
