12 Pi Day products you didn’t know you needed, but do

Pi Day is just around the corner! On March 14th, fans of math and pie come together to celebrate π, which is the ratio of the circumference of a circle to its 3.14. They often do so with a great deal of humor, and I was cracking up at some of the fun items I found to help make your Pi Day as fun and festive as possible. Here are Pi Day products that you didn’t know you needed, but do.

Pi Pie Pan

How perfect is this pi pie? I love this pie pan so much. So. Much. Forget the fact that I have no idea how I’d actually make a pie crust for this.

Pi Cookie Cutter

Less ambitious bakers may find that this Pi-shaped cookie cutter is more up their alley.

Come To The Math Side We Have Pi T-shirt

Star Wars and Pi Day together? Yes, please!

Pi Superhero Shirt

I’m also loving this shirt.

Pi Socks

Because footwear matters, and so does Pi.

I Ate Some Pi And It Was Delicious Travel Tumbler

This is “I 8 sum” pi, or “I ate some Pi.” Pi humor and warm coffee equal a great morning.

Pi-Shaped Teak Shower Bench

Okay, it’s pretty likely that you don’t actually need this shower bench, but if you’re married to a math major like I am, it could be a big hit.

3.14 and PIE Coincidence Tall Mug

I do not think it’s a coincidence, do you?

Pi Mouse Pad

I don’t use a mouse any more, but I kind of want this anyway.

There are also several great books on Pi, including:

Sir Cumference and the Dragon of Pi by Cindy Neuschwander

The title of this book has me wanting it, regardless of the fact that Amazon recommends it for kids in middle grades.

Why Pi? by Johnny Ball

The book Why Pi? examines on how Pi and numbers in general have been used to measure things, from how the ancient Egyptians measured the pyramids to the ways that current day scientists calculate time and space. Amazon says it’s best for grades two through five.
