Mattel Belt Buckle Gun

In 1959, Mattel introduced the Agent Zero Buckle Gun — a belt buckle holding a small gun. To fire it, kids had to push out their stomachs, which would make the gun flip out and fire the cap. . While kind of cool in principle, the toy had a major flaw: Any sudden movement could accidentally ignite the cap, potentially causing serious burns. With the CPSC not yet established, it was up to Mattel to do the right thing. The company quietly discontinued the dubious belt buckle gun — a toy that would be instantly banned today — consigning it to the annals of dangerous toy design.
