I grew up out in the boonies with 6 brothers and sisters, Dad owned an excavating business and along with all the heavy equipment came the workshop and tools to repair them. Older brother and I would get balloons, fill halfway with acetylene and top it off with oxygen from his cutting torches. Put the balloon in a paper grocery bag, twist the neck of the bag up tight, set fire to it and run like hell. Home-made Daisy Cutter. We would clear out spots to pitch our pup-tent for camping expeditions down by the river. Also used to take M-80s (back when you could buy real M-80s), smear them with contact cement and roll them in BBs. I am still amazed that nobody walked away with a bloody stump.
