Cai Guoqiang created a firework stairway to heaven in celebration of his grandmother's 100th birthday in China.
The stairway took place earlier this year in China, and was created using a large weather balloon that is lifting a 1,500ft wire ladder that was covered with fireworks and gunpowder before being attached it to the bottom of a hot air balloon. Guoqiang tried to make his firework ladder several times over the last 20 years and this is the first time it was successful. During the celebration of his grandmother's 100th birthday, Guoqiang stated that he "wanted to put on a spectacular fireworks show to thank his grandmother for supporting his dream of being an artist."
Here is some of Guoqiang other work.
