Every year the same tired old story.

I wasn't there, but a good friend relates a 4th event preceded by, "I'm a chemist, I know what I'm doing."  What he did burned a 10 ft hole in someone's yard and put said chemist in a burn unit for four months.  Having know the chemist for several decades, the story is easy to believe.

Except the "marrying the nurse" part...

I went to a block party where some of the folks had illegal fireworks. Instead of using the mortar tubes they came with, they made some out of PVC pipe. Since the diameter was different, one of them simply rang around the inside until it finally escaped out the side. The lift force being spent, it blew up on at about 8 feet out of the tube, shooting sparks all around. Nobody got burned, so they went back to using the cardboard tube that came with them over and over. I was waiting for it to blow out, repeating the first farkup. Later something shot below a car and blew up. Nothing serious happened, so no lessons were learned. Everyone involved eventually moved away. Such as it is in Las Vegas.
