How to Celebrate
The idea behind Pi Day is to celebrate Pi, the mathematical constant representing the ratio of a circle's circumference to its diameter. Pi is a decimal of over 10 trillion digits, however it is most affectionately referred to using its first three digits, 3.14 – which also happens to be today's date, March 14 or 3/14. You can celebrate Pi Day by eating pie, you can challenge yourself and friends to see how many digits of Pi you can memorize, you can watch "Life of Pi", take the Pi Day Challenge or — especially for you geocachers — you can attend CaptainMath's annual Happy Pi Day! event.
To honor this day we are featuring the 1995 V8 Pi can. This was a very limited edition can of mild V8 vegetable juice given out as a promotional item at the NCTM (National Council of Teachers of Mathematics) Annual Meeting & Exposition that same year.
Just kidding… here is the real can. It is the 1995 V8 Picante Mild Flavor Vegetable Juice can. Yeah, it's a stretch, but the top of a can is a circle. Someone really needs to make a Pi beverage.
Happy Pi Day (3.14)!
