OK How ? LOL
We were running several tubes a few years ago. My son and I were doing the display and one of his idiot friends wanted to help and did not tell us. He dropped one in upside down and went to light it. I saw the short fuse and knew it was in wrong but could not stop said moron from lighting the fuse. Screaming as I tackled him and my sun running the launch charge fired and the display blew the tube in half as it did its 750 ft. wide thing.
Minor burns only and the idiot was pissed that I tackled him.
