Check out this 80-story high fireworks show.

Ever since its release, this fiery 80-second art installation has gone viral. In what appears to be a ladder made of fireworks, this art installation by artist Cai Guoqiang, took place in June in Quanzhou City in China’s southeast Fujian Province. The spectacular display of fireworks, which he calls Sky Ladder, has been referred to by some as a “stairway to heaven,” and it was dedicated to the artist’s grandmother, who just celebrated her 100th birthday.

This was his third attempt at doing this and if you’re wondering how the ladder was held up, well, he used a weather balloon to pull up the 500-meter long wire ladder that was equipped with fireworks and gun powder.
