This is something I've always wondered. Bombs. Specifically, movie bombs. The hero is always wondering which wire to cut in fear of the thing going off. Surely the safest method is to simply grab the catalyst and yank it out of whatever they're using as explosive material? 
Another one is that in many films / shows, if they cut the correct wire, the clock simply stops. That makes no sense either.
This is confusing me.
Help.
