Enjoy a refreshing drink in this rocks glass and test your memory of the numbers in pi, the mathematical constant that is the ratio of a circle’s circumference to its diameter. The decimal representation of pi never ends, and hundreds of the decimals are etched onto this glass. On the other side, the equation for pi is printed, along with an illustration of it, proving that nothing is more elegant than mathematics.

This glass is a perfect gift for the mathematician or trivia fiend in your life, or anyone with a thirst for knowledge. 

Don’t forget to celebrate Pi Day each year on March 14th, since 3, 1, and 4 are the first three significant figures of π. Pi Day was founded in 1988 by Larry Shaw, an employee of the Exploratorium, a science museum in San Francisco.
