Launching bubbles for "FACES 4 Autism"

WAYNE, Pa, (WPVI) -- Students in Delaware County got to have some fun Wednesday while raising awareness about autism.

They blew bubbles as part of this second annual event at Wayne Elementary School.

The children lined the school's driveway with suds in hand.

This was part of a worldwide event created by the non-profit "FACES 4 Autism."

The bubbles are said to be symbols of hope to families with autistic children.
