Exellent. Sounds well thought out. But 20+ is still a shitload! Better bury it deep.. what kind of earth is afoot there? Dry and shitty? Rocky, or sweet creamy damp topsoil? I gotta admit I have kind of a thing for mud... moist but not soggy, rockless (important!), no giant roots.. Love putting holes in it!!
I think there is an ideal mix of water/dirt ratio that responds best to the hydrostatic impulse of the shockwave, without extra water to absorb the energy.. Hard to nail down or find but you definately recognise the result!! |
