   Being an electronic lab tech with a chemistry degree I have been the   
   stuckee for UL-type "safety" experiments involving blowing up charging   
   lead-acid batteries and similar devices with accident potential. I   
   also set off a few model Hindenburgs, spray cans, fire extinguishers   
   and other lab and home pressure containers in remote sandpits out of   
   curiosity. Sharp-edged metal container fragments can fly a long ways   
   and still have enough energy to stick into trees.   
      
   The hydrogen-filled Hindenburgs turned out to be tame enough to use as   
   indoor college pranks. They only rattled windows when the firecracker   
   ignited the balloon, with more WHOOMP than bang despite some air   
   inside. For context other students were depth-charging the sinks and   
   toilets to pieces and shooting squirrels from the windows.   
      
   Hydrogen may require unique and specific handling procedures but it   
   doesn't explode any more violently than other gases, except acetylene   
   which reputedly can detonate under pressure. These aren't the times to   
   be Googling for references on it.
