Manchester explosion
I am reminded of some experiments I did around 40-45 years ago, filling relatively small (1 foot diameter) balloons with stoichiometric https://en.wikipedia.org/wiki/Stoichiometry mixtures of hydrogen and oxygen (or another fuel gas and oxygen, example propane), if ignited they produce remarkably loud-sounding, and yet low-pitched "booms": Sounded like a huge explosion done a long distance away. Yet, there was no possibility of shrapnel, other than a thin rubber membrane. This could easily scare people in a crowded venue, causing panic and crushing crowds. Perhaps this explains what is being reported as happening in the Manchester arena. Jim Bell

Yes, I did that as a kid. I used much larger plastic bags, however. But propane and air, because that's what I had.
