Drones have been used for many things. Fore surveillance, bombing, and even pizza delivery. (Pizza delivery was just a a stunt commercial.) But it is used mostly for things that we do not want.

But Carel Hoffmann, director of the Oppikoppi festival has made a good use for a drone that everyone will be happy about

Johannesburg: Revellers at a South African outdoor rock festival no longer need to queue to slake their thirst — a flying robot will drop them beer by parachute.

After clients place an order using a smartphone app, a drone zooms 15 metres (50 feet) above the heads of the festival-goers to make the delivery.

Carel Hoffmann, director of the Oppikoppi festival held on a dusty farm in the country’s northern Limpopo province, said the app registers the position of users using the GPS satellite chips on their phones.

“The delivery guys have a calibrated delivery drone. They send it to the GPS position and drops it with a parachute,” he explained.

The nickname they gave the drone is “Manna”
