explosives

I know E/D didn't use all of there ammo on the day of the shooting. But does anyone know if E/D used all of there pipe bombs and other stuff the made?

I just finished a part in Cullen's book that describes approx a hundred explosives were found in the school altogether. Most had detonated. Some, thankfully, had not. I would hazard a guess and say this info is probably reasonably correct despite its source. I think the boys used pretty much all they had made.

Thank you
