Pi Heat Change Mug

Update: The Pi heat change mug may not be available anymore but be sure to check out the Pi t-shirts on the Shirt List.

You don’t need to be a mathematician to appreciate this Pi heat change mug but of course, if you are a mathematician you might appreciate it more. It was sold by ThinkGeek but they don’t seem to have it anymore.¬†Each Pi By the Numbers Heat Change Mug is covered in Pi. When it’s cold, the mug displays Pi’s nickname: 3.14. But when you fill that same mug with hot caffeinated* liquid, Pi majestically unfurls around it to 334 decimal places. The name by which mathematicians and physicists and astronauts and engineers and generally people interested in precision know Pi.
