They called it ‘controlled’. I have no idea, unless they haul it to vacant area.
I recently watched a show on TV called ‘Future Weapons’ which features new weapons of variuos designs.
One of the weapons featured which is manufactured in Britian is a specially shaped water can similar in SIZE to a WWII Jerry (gas) can. This plastic device is filled with water and directs a stream of water when detonated which rips apart anything near it including artillery shells and other explosives without them off.
On this particular show, it was shown being used on a car which had a few artillery shells (IED’s)in the trunk.
The explosion ripped apart the rear of the car and sent the projectiles a considerable distance away. In the process of detonation, the ‘explosion’ rips apart any wiring and controllers which may be used to detonate the IEDs. Since the ‘explosiion’ is mainly a focused water jet, it doesn’t set off any other explosive material which it may be used against.
To “control” an explosion, you first detonate the explosive, then, watching the explosion closely, when it has exploded the amount you want, you stop it.
