Materials:  2-3 in. section of pipe
                PVC (for test and fun)
                Steel (for shrapnel)

            12 guage shotgun shell
                (fitted to pipe)

            marble
            ping pong ball
            cap for pipe

            2-3 ft. ribbon
                (flights)

            explosive charge
                (of personal preferance)
                a 1/2 or 1/4 cup petrol makes an excellent charge when
                vaporized filling the pipe with gunpowder is simplest
                or any STABLE flammable explosive one may have.

    This design  is  a  modified  pipebomb  which will be set off upon hard
contact.  This  makes things much easier than tossing molotove cocktails or
lighting fuses as all you do is throw it and it should detonate on contact.

 1)  Cut the plastic of the shotgun  shell off of the primer and set aside.

 2)  Carefully fit the  primer into one end of the pipe and epoxy securely.

 3)  Glue the marble to the 'dimple' of the primer.

 4)  Cut the ping  pong  ball in half and then glue half onto the marble to
     make a simple form of casing.

 5)  Put explosive charge into the hollow pipe (if useing gasoline use only
     1/4 of the  volume  of  pipe.  Reason: 1 gal. of gas vapor = 16 sticks
     dynamite!!!).

 6)  Cap the pipe and epoxy into place.

 7)  Tie ribbon around tail section of pipe.

    Relax.  Now that its finished  heres  how  it  works.  When  thrown the
grenade will come down upon the point because of the tail flights.  When it
hits, the primer will be crushed by the marble, setting it off.  The primer
then ignites the explosive charge.  I  heartily  recommend that PVC be used
for testing as the steel pipe is  rather  dangerous.  This  design is not a
toy and should not be built to be played  with.  If  you  want  a  toy just
empty a shotgun shell and tape a marble to the primer  and throw.  It makes
a quasi-safe firework.
