Hundreds of drones lighting up the sky in China dropped to the ground after a sudden glitch during a night show in Guangdong province in 11 August.

The show was reportedly held at a zoo in the town of Liaobu.

Colourful drones that were forming patterns in the sky suddenly crashed in unison during the performance, prompting gasps from onlookers.

A zoo staff member later told local media that there were approximately a hundred drones being used in the performance.
