Wow, I wonder how they did that.

I had a book on making pyrotechnics when I was a kid (it was an old how to book, like from the 1930-50's).
It explained how things like different colors and starbursts and secondary bursts at the end of tracers from a primary burst, but I don't know how they make the rungs so well.
Or why they last so long.

Not normal stuff. Some trick is going on.

I think they hang a ladder thing from a balloon, so the structure is already there.

I agree with the wizard. I think they floated it up with a balloon and then lit it off. A rope ladder structure soaked in gunpowder or fireworks powder.

""Fact: the man that created this display is from China and had been working on this since 1994. He called it "Sky Ladder" while envisioning a stairway to heaven...regardless of what everyone thinks or believes it is or isn't. He was able to display it for his mother's 100th birthday. It is a 500m wire ladder attached to a weather balloon. The ladder was then covered in fireworks and gun powder. ""
