Canary Cry (object)

The Canary Cry is a non-lethal weapon created by Cisco Ramon for Laurel Lance that projects a sonic blast when used.

History
After Laurel Lance approached Cisco Ramon, he refitted her sister's sonic device to work in a collar, though more powerful; Cisco quadrupled the range of the sonic blast and tripled the resonance. In return, she gave him a picture of him and the Black Canary together.
