First get a pipe with 2 screws able and unscrew able ends put the bottom end on.
Next drill a hole in the top one for the fuse.
Next put tissue paper at the bottom of the pipe then fill the inside tube up with explosives E.G. gunpowder from fireworks or from a gun store.
Then pack the fuse in and around the gunpowder then put the end out the drilled hole.
Next put some more tissues in the top of the pipe and compact the gunpowder (explosive) Screw on the top making sure the fuse doesn't snap and there you go, a pipe bomb!
