Vizualizing the Digits of Pi with Popsicle Sticks

We have utilized wooden popsicle sticks to create a simple, beautiful and physical representation of mathematical constant π (pi).

The infinite constant pi is the ratio of a circle’s circumference to its diameter. For any circle if you divide the distance around the circle by the distance across it, you will get pi or 3.141592653589793238462643383279502884197169...

Each digit of pi is represented by a stick, a circular representation of pi, where the numbers are linked across a circle with a stick.

Step 1: Materials and Tools


- Wooden popsicles sticks

- Glue


- Power drill

- Protactor ruler

- C clamp

Step 2: Assembling

a) Drawn a radius every 36 degrees (360/10), each radius is one digit from 0 to 9.

b) Take the sticks in groups of 10, following the digits of pi, the first sequence is 1415926535, the second is 8979323846. Glue every stick according to their digit.

c) Drill a hole in the first group. Glue each group with the help a clamp. Any height is ok, in this project we use 40 sticks representing the first 40 digits of pi.

d) Use a wood block as stand
