The case in Michigan was a 1977 lawsuit by the family of a 12-year-old against a company that manufactured slingshots. The boy was injured when he was struck in the eye by a pellet fired from a slingshot that ricocheted off a tree. The court allowed the case to go before a jury, ruling that the company entrusted the slingshot to a class of people, in this case younger children, that made the ultimate accident foreseeable.
