and if it was inside a container, which was able to be affected by a taser in a manner that developed a spark, there would have been a bit more of a boom or pop when the container then exploded (the severity of which would be related to the material the container was made of, and how strong the seal was)

Ohh, bonus, I actually didn't watch the video in the article--I saw the un-clipped video elsewhere on reddit prior to seeing this article. The one in the article cuts right when he hits the ground, to about ten seconds later. In the un-cut video, he fell and rolled, and caught the taser while we was rolling. He definitely crushed that can.
