Some tape their mouths shut as part of a youth movement to raise awareness of harassment, prejudice and discrimination.

The sounds of the high school band Cosmic Infinity reverberated through Corona del Mar High School’s quad Friday, drowning out the conversations of students eating lunch.

As the music geared up, students celebrated breaking the silence, with some pulling pieces of tape from their mouths and speaking for the first time that day.

“I want people to know they are definitely not alone and they can speak up and they have a voice,” said freshman Savannah Bachelder, 14, who is part of the Humans Relations Council.
