Three big UK retailers, including Amazon, are telling customers to throw away hoverboards because of safety worries. There have been reports of them exploding. Consumers will get a refund if they take their hoverboard to a recycling centre. Hoverboards are like self-balancing, two-wheeled skateboards. They are a very popular gift this Christmas. The retailers' decision will disappoint many children.

A consumer group in the UK said half-a-million people bought a hoverboard as a Christmas gift. Another million people have it on their shopping list. Britain's largest store said: "We've suspended the sale of all hoverboards…as a precautionary measure." Amazon said: "We regret the inconvenience…but trust you will understand that your safety and satisfaction is our highest priority." Hoverboards are not allowed on public roads.
