As all young boys we have the ability to hear , see and remember, things that adults don't think we heard and remember and can figure.
My grand father always seemed to have Dynamite around , he used to remove stumps and large rocks. But what he was good at was telling stories. He told a story of blowing up ice damn in the narrow of the river down stream from the farm ,the water was backing up and he was afraid the river would flood and take out the homestead and barn. he tossed a stick of the dynamite onto the ice with a what he thought was a long fuse. long story short the narrows it now no longer narrow or shallow.
My brother I had heard a story about my dad and how he would use dynamite to catch fish. we thought it was worth trying. we got what we thought was 1/4 stick of dynamite a fuse and cap and headed to the river. needless to say a 1/4 stick is bigger then you think, a fuse burn faster then it's supposed to, and short legs don't' run as fast as long legs. as a result of the fishing there is a new swimming hole. The old well that had dried up start filling in , and grandma had some of the best tomatoes and roses from the carp we had to haul back to the garden.
