Pi Day Celebration at the Cincinnati Observatory

Join us at the Cincinnati Observatory as we celebrate the magic of pi (π) with an evening of fun for all ages.

Uncover the secrets of pi: Explore how this incredible number has shaped our understanding of the universe through engaging presentations and interactive demonstrations. The Event will take you all around the Observatory with out-of-this-world prizes for those who finish our scavenger hunt. Weather permitting, gaze through our historic telescopes and witness the wonders of the cosmos.

Don’t be a “square,” come celebrate Pi Day with us!

Pi day just wouldn’t be complete without a pie in the face!

Our staff members are crazy for pie. You can donate to the Observatory using our new Venmo account – @cincyobs. The top 3 staff members with the most money will receive a whipped cream pie in the face, and the additional fun part is that those who donate $5+ (and hold a valid entry ticket to the Pi day event) will be entered into a drawing to throw the pie!

Be sure to enter your Pi(e) “target” in the memo line when donating. Choose from Dr. Wes, Anna, Mika, Nicole, Natalia, or Mandy.
