Filled with gunpowder,150 oak barrels floated like piano keys on the Charente River in Cognac,France.After a five-second countdown,21,915 fireworks of green,white,gold and orange launched from them to the sky,kicking off a 15-minute daytime display.The September 2020 spectacle was the work of artist Cai Guo-Qiang for the 150th anniversary celebration of cognac brand Hennessy X.O.
