Remember the days of calculating circumference in math class – the moment when you were introduced to pi? Oh, what an absurd number 3.14 (etc. etc.) is – if you ask your average mom or dad, anyway. But using pi to cut a slice of pizza pie? Well, now we’re talking. Take a look at the Pizza Pi Cutter!
Available in three colors – red, black and lime green – the plastic pi features two steel blades that cut the perfect slice of pie. This pi-shaped slicer, also an homage to the 16th letter of the Greek alphabet, is easy to grip and cuts each piece with ease. That makes it a breeze to teach your kids some basic kitchen math (extra credit!). Purchase this cool cutter online at ThinkGeek.com for $9.99.
