A ComEd sweepstakes winner will once again revive the fountain.
This is the seventh year that ComEd partners with the Park District for "Switch on Summer."
The fountain is one of the largest in the world and is located off of Columbus Drive in Grant Park.
It typically runs from 8 a.m. to 11:00 p.m. from May through Mid-October, according to the Park District's website
While in operation, the fountain shoots out water up to 150 feet into the air and is on display for 20 minutes every hour, the website said.
