Explody Pen Gun! Simple and Cheap!





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

    i reckon thats a pretty cool gun. it would freak out people in the classroom setting!

    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.

    a party store, like nobbies or maybe factory card outlet. or the internet. lol everything sells on the internet.

    Most 'Party' stores, local supermarkets have them in the 'party' section [might be near the lollies]

    Pretty cool haven't built yet but i will definetly get some poppers to build this how far does it shoot

    u can get party popprs in belingham at a place called olde english crackers

    for ammo it is usfull to use bbs but when you run out i use tic tacs as you can suck them down to fit the barrel perfactly ps.sorry for the spelling
