Introduction: Explody Pen Gun! Simple and Cheap!

Pen Gun that fires via combustion, very cheap and simple to make.

Step 1: Gather the Parts

This is my first Instructable so i hope you learn from it, my computer has been screwing up lately so sometimes things dont work anyways enjoy.

Parts needed

Party Popper
Pen with detachable front part (you will see)
Ammo (NEEDS to fill the barrel with NO air gaps)

Step 2: Take Apart the Party Popper

Remove the base of the popper, (made from cardboard) then take out the string stuff, remove the next cardboard peice then very carefully take out the "popper".
To help remove the popper part, push in the top and then remove.

Step 3: Put It Together

Get the pen lid (the removal part) and insert the "popper's" string end to the writing hole.
Screw the lid with the popper back onto the main pen part, insert your ammo and pull hard on the string.

Step 4: After Firing

After firing get some wire or the like and stick through the pen hole to eject the used popper, to reload do the whole process again!

really fun, but i used pull string fireworks, they are pretty much the same thing as the poppers string, and cheaper too

Probably give off barely enough force.I tried to make a shotgun with a popper by filling it up, it launched 3 bbs like 5 feet. Use plastic ones "airsoft".

in england you can by them anywhere, for really cheap, i just bout 100 for £2 today because its my last week of school for life lol, so im making a door bomb to scare my music teacher.

Which is good because they are the only explosives we can buy - I am trying to set them off electrically for miniature explosions in films.

Oh and I found and easier way to get them out of the plastic casing, on the ones that I buy you can just cut them at the point where the handle joins the streamer container at pull the charge and string straight out.

me and my mates made this instructable at school and it rules but we started to get ideas and started to use other things like bbs metal pellets *the metal pellets are the best so far because they hurt*(especialy at point blank range in the back of the leg or top of the spine)
