Felling a Tree at Height!

BP is a Class A Explosive, where the components of Rack-A-Rock are just HazMat Chemicals, until mixed together, and are available in ANY Quantity, to ANYONE. BP is limited, in amounts that can be stored, locally, by BATFE Regulations, and the local Fire Marshal, without an ATF Magazine License, which is a GIANT PITA, if you have ever had to deal with that. BP Deflagrates, (Burns) where Rack-A-Rock, Detonates. This gives it a much nicer Pressure Curve for Heaving Things up out of the Ground, as well as Shatter Velocities, that make the "ToothPick" Senerio work. To FAST and you do not get Heave Capability, to SLOW, and No Shatter Capability. BP is way to SLOW, where Most HE, is way to FAST. Cheddites are right in the middle, and just the trick, for the JOB.... and NO, "Big Stuff" doesn't designate what Energetics require Booster Charges. That is determined by the Entropy Knee, of the Energetic Itself. Some Energetics Do, and many do NOT... It is specific to each Energetic. ANFO DOES, but Tovex, does NOT, and both are Basic Ammonium Nitrate based Energetics...

 

A bit of clarification is in order here. BP deflagrates, meaning burns, and the pressure wave front is by definition subsonic that produces a relatively mild destructive wave front. Detonate is also an oxidation reaction (similar to burning in that respect) but the flame front is supersonic and creates a pressure wave that does the destruction. Between stuff like BP and (say) C4 or anpho, there is a range of explosive mixtures that can be tailored for the desired effect. Rackarock is but one. Do Not try these at home lest your kids become orphans or you want them to inherit early.

 

Cheddites are binary Energetics, in that they are just HazMat Chemicals, until mixed, then they become an Energetic, in the same way Tannerite does..... I haven't dealt with BATFE, since 9-11, so I am not up on the latest Rulings, however back before that, Cheddites were not regulated, and could be shipped UPS Ground, as just Chemicals. HazMat Shipping Rules may likely been changed, since then, as well, but I bet I Could order a 50# Can, and 2 Liters of the liquid, by Truck Freight, and get it delivered, especially if they came from different Chemical Supply Houses.
