Fidget spinners may be America’s most popular cheap toy, but a Boston-based advocacy group says they’re also pretty dangerous. In its annual summer safety report, World Against Toys Causing Harm lists fidget spinners alongside hoverboards, plastic weapons and non-motorized scooters as the most potentially hazardous summer toys. As the AP notes, children in Texas and California were recently hospitalized after choking on fidget-spinner parts, while German customs officials destroyed 39 tons of spinners over safety concerns.
