It's like starting a chain of dominos, if they were just piled together and exploding.
The origin of this specific video is lost in the mire of Google Translate (c'mon, Google, it's not like Americans' amazing multi-lingual abilities are at risk of atrophying, just do it for us!), but it's almost certainly from Taiwan and the title of the clip definitely (maybe) translates to "Taiwan-Style Nuclear Burning Firecracker." One thing is for sure, however, which is that I wish I could be in the first row for this event. Well, the second. Near an exit.
The good stuff starts at around 1:20.
