5. Lawn Darts (Jarts)

The once-popular outdoor game known as lawn darts or “Jarts” featured heavy, metal-tipped darts meant to be tossed toward plastic rings on the ground. Unfortunately, their design made them extremely hazardous—many children and adults suffered serious injuries, and some accidents were even fatal. After repeated incidents and growing public concern, authorities banned these dangerous toys, transforming them from a backyard staple into a cautionary tale about the need for safer playthings.
