Sonic Blaster, 1966
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.
You can't make up stuff this good and Consumer Reports has a whole section of their site devoted to the vintage tech. How we lived, breathed and loved before today, we do not know. [Consumer Gallery via bbGadgets and Laughing Squid]
