At first i was extremely skeptical that you melted copper with petrol but now you say you ruptured copper with petrol? now even if you sealed the barrel off completely there is no way petrol could produce enough pressure at normal oxygen concentrations to rupture copper pipe.Oh and is there some reason you cant post pictures?

Yeah, It's B.S. to the max.
It's either a cry for attention or it's wildly wildly wildly exaggerating an incident.

At school he told me that the PVC melted but the copper didn't. It makes no sense.

Does this sound to anyone like DDT? I know it doesnt happen in combustion cannons but... :? :bs:

I would believe it with petrol and pvc. not copper, unless you sat there with thermite and a blowtorch.

besides something like that shouldn't be here at all, and should be in a "how to injure yourself" guide.

If you filled the whole chamber with petrol, nothing would happen.

Well I've given him a massive bollocking, He said he's left Spudfiles for good becuase he thinks "your all losers". He didn't even know how a combustion gun worked when he joined and he came on like he know everything.
