Visiting a China trade show for fireworks manufacturing machines

Above, a visit to a building in Liuyang, China where stacks of roman candle tubes and pop-its cover the floor. This is a fireworks machine trade show, where companies purchase contraptions for cranking out explosions of all kinds. Liuyang is commonly known as the fireworks capital of China. Here are some of the captivating machines that make (or break) July 4th and New Years Eve in the US.

And as a bonus, here's a video of another machine that was used for manufacturing M-80s before they were outlawed in the US in 1966 (unless you have a license):
