Well, if your wife's father passed away a while back, and he was really into shooting muzzle loaders, and had a 58 cal rifle, and had a crapton of rubber tubes full of FFFg black powder, stuffed at the open end with a minie ball and you pulled the ball for melting and casting later and emptied the powder into a plastic peanut butter jar that was about 2.5 inches diameter and 5 inches tall and it got about 2/3 full and probably weighed about 12 ounces and you put a fuse cord into the lid and glued it in place and glued the top on proper and lit it and threw it down the field and it landed about 50 feet away and took about 20 seconds to blow up from there due to the long fuse and you were able to feel a bit of the concussion wave from that distance I think it would make a fair bit bigger hole in the dirt than you got if you buried that jar mostly full of powder a foot or so deep. But of course this is all guesswork.
I don't know anyone who makes bombs or knows how to make a bomb or even thinks about making bombs or even thinks about trying to learn how to think about making a bomb, but if I did I think they would tell me that was a bomb.
