A Hoverboard Catches Fire

Hoverboard On Fire

They used to be the name of levitating boards that look like skateboards without wheels, used for personal transportation as seen in the movie Back To The Future II & III.

Nowadays, 
hoverboards are self-balancing, two-wheel boards
which are portable and rechargeable battery-powered scooters.
And obviously,
these scooters don't lift off the ground or hover
as their names suggest.
Each hoverboard has two small platforms between the wheels
on which the rider stands
with built-in gyroscope and sensors.

These scooters are gaining popularity 
that they are gladly used by young and old alike
at home or outdoors in the park.
But a lot of incidents have been reported already
regarding the hazards of using them.
Some of them caught fire 
and even exploded during charging.
Some airlines already banned them too.
