As a way to make my detonators a little stronger, I decided to make use of the little vial of nitroglycerine I have standing around.
So I wrapped my standard detonator (0.5 grams of AP in a 6 mm thick straw) in 1 mm thick cotton wire,
(3 layers) and secure it around the the detonator, over the area where the AP is located.
Then this is soaked in nitroglycerine, by letting it absorb in drop by drop. (about 2 ml of NG)
right after dropping the nitroglycerine on the cotton cord (letting it soak a bit)
Taping up the part of the cord that is just soaked ...
And then we proceed by filling the detonator. First the AP, and then the fuse part in BP.
So when passing the previously made crater in my backyard (by similar, smaller charges),
I take my little shovel to dig a new blasthole.
As you can see, this blasthole is quite a bit deeper then the last ...
The fuse barely sticks out of the earth
The thrill of lighting the fuse, and taking a picture of it, and thus,
burning my hand a little (note the shakey pic on the right) aww, BP burns !!
Just like with the last little tests, all of the earth was blown out of the blasthole ..
The sound was quite impressive this time, even if it was burried under 30 cm of dirt ...
