What happens when 20 lbs of C-4 explodes?

Read to the end and you will see…

C-4 is classified as a high-order explosive (HE), that produces an over-pressurization shock wave.  It is similar to TNT, Semtex, nitroglycerin, dynamite, and ammonium nitrate fuel oil (ANFO).

It is very stable and cannot be detonated by a gunshot or by dropping it (unlike the explosive TATP, commonly referred to as the “mother of Satan,” because it is highly susceptible to accidental detonation).  In order to detonate C-4, you need to utilize a detonator or a blasting cap.

Because of its stability and destructive power, this explosive has garnered the attention of terrorists all over the world. A small amount of C-4 can do a lot of damage, and when you add just a little bit the effects multiply. The U.S. military is the primary manufacturer of C-4, and it tightly guards its supply, although there have been numerous instances where blocks were stolen from supply depots.  Also, Iran produces an explosive with similar qualities called RDX, which it exports it into the hands of just about every terrorist organization.  As long as C-4 and C-4 like explosives are readily accessible, it will continue to be a primary weapon in the terrorist arsenal.

Ok, now that you know a little bit about C-4, let’s see what happens when 20 lbs of it is placed next to a vehicle (FYI —I return to this imagery when writing scenes in my stories that involve explosives)…
