The concept behind this toy could be seen as either kind of cool or a bit disconcerting. Brought out in 1959, the idea was your child wore a toy gun on a belt buckle around their waist and when they vigorously thrusted their hips forward, causing the gun in a hands free motion to swing out of the buckle. Seemingly of its own accord and open fire.
The reality was that the gun would jam setting itself and the buckle on fire, threatening to set your kid alight too. The toy was banned and withdrawn the same year it was launched.
