blow up doll
1] get your basic ken doll [ barbies boyfriend ] should be named jack due to lack of basic man parts
2] about 4 ounces C4 or semtex plastic explosives
3] roll plastic explosives into a tube and shove it into the jackhole [ it is called this because like its namesake the ken doll has a mouth ]
although lacking the aforementioned man parts
4] insert blasting cap [ i reccomend a fuse type] into the plastic explosives [ i dont have time to give a lesson on solid pack, fuse head or bridgewire caps at this time ]
5] attach wire from cap to detonator and the rest is self explanatory [ if not send of for your own copy ] or learn it the hard way
