Ladder-shaped fireworks

Back in June, Chinese artist Cai Guoqiang has successfully carried out his third attempt at his pyrotechnics project Sky Ladder, an installation that recreates a ladder made of fireworks in the sky.

A gigantic white balloon filled with 6200 cubic meters of helium and with a 5-ton pulling force slowly dragged a 500-meter long, 5.5-meter wide ladder lined with quick-burning fuses and nozzles of gold fireworks high into the sky. Cai ignited the ladder from the bank, causing dazzling flames to race along the beach before climbing onto the platform where the ladder was first laid out. Hissing violently, the flames rushed upwards as the golden ladder of fireworks rose steeply from the ground, curving elegantly against the backdrop of the dawn sky. After 60 seconds, the fireworks started to die out from the bottom up, bit by bit, as if the ladder was moving upwards, leading the viewers to look up and converse with infinity. The explosion lasted a total of 150 seconds.
