Past Event

Everything's Cooler by the Lake!

SOLD OUT. To put your name on a waiting list for unclaimed spaces, come to the registration table at the west ramp to the red seats at the Pritzger Pavilion between 4:30 and 4:50 pm. Unclaimed spaces will be distributed on a “first come, first served” basis at this time.

Why do you see yourself in different shapes in the Bean? How does the sound of music travel from the stage of the Pritzker Pavilion? And why exactly is it always cooler by the lake in the summer?

This program will explain the science behind three Millennium Park phenomena: the optics in the Bean (Cloud Gate by Anish Kapoor), the acoustics at the Pritzker Pavilion, and the lake effect.

Audience members will travel to three different points to hear each presentation: in the red seating section area at the Pritzker Pavilion, underneath the Bean, and on top of the Harris Theater.
