Mayor Mike McGinn announced Tuesday they'll be melted into plaques that feature quotes from Seattle children about gun violence and how it affects them.
Students can submit quotes in the "Weapons to Words" contest to the mayor's office. Winning entries will be selected by Sept. 15. The plaques will be placed in Seattle parks.
The program is supported by Schnitzer Steel and the Chihuly Studio, which is helping to design the plaques.
The buyback program was announced a month after last December's elementary school massacre in Newtown, Conn., by city leaders sick of hearing about gun violence. Some 716 guns were turned in.
Students can submit their quote of 50 words or less to www.seattle.gov/mayor.
