The Zero M Sonic Blaster — 1960's Loud Toy

This commercial features a young Kurt Russell, with narration by William Conrad, demonstrating a Mattel toy called the Zero M Sonic Blaster. It's anybody's guess as to how many children suffered injuries to their hearing from this powerful, dangerous toy. You could also put dirt and rocks into it, as ammunition, to shoot at whatever you felt like.

Consumer Reports magazine: "The Mattel Agent Zero M Sonic Blaster 5530 fires compressed air with a deafening blast. Our measurements top out at 157 dB–above a level that can do permanent damage to the hearing of an adult. We rate the toy Not Acceptable."
