The Wings of Zadar cocktail, based on the local Maraschino liqueur, is poured upside down so that the drink flies upwards into the mixer, and then shaken as the barman performs a series of somersaults.

The drink is chilled by the freezing air rushing over the shaker - and then served on landing to the customer.

Drinks creator Ante Butic, who has been serving the drinks to clients on the beach at Zadar, said: "The high altitude mix gives the drink a distinct flavour.

"It is really popular, the service is sponsored by the local tourism board but who knows, maybe I might carry on if I can find enough rich customers who want to try the ultimate cocktail."
