Introduction: Bic Rocket Launcher

Today: a rocket launcher made out of a bic mechanical pencil.
Tomorrow: mini warheads

Step 1: Gather Materials

you'll need;
a bic mecanical pencil,
some scotch tape,
thread or other fuse,
propellent(I used match heads,
and a vice grip or
other means of breaking off the cap

Step 2: Crack It Open

Break off the cap and anything in it (after removing the grip)then pull out the led cartridge.

Step 3: Final Assembly

Tape the cap to the part where the eraser used to be and put the grip in the clip as a sight or grip.(optional)it should look like the second image

Step 4: Final Prep

insert a 4 or so in. long piece of thread in the hole in the back of the ammo then put in your propellent of choice.Matcheads work fine especially if you crush them into a powder.

Step 5: Troubleshooting

you can't figure out how to fire it:the cat is smarter than you
you want to sue me:for what you did all on your own?
you are bored:get lost

Sarcasm is the worst sense of humor. This does not apply to me.

I recommend the "macro" setting on your camera. It will be represented with a little flower icon and is most helpful in focusing on close-up objects.

Why do you find it "stupid and confusing", would you care to explain so I can improve it?

I like using copper pipe with one end flattened down and a hole drilled in it it works fine.

Try keeping your face away from the exaust. The rocket will not explode...

any other possible prjectiles asides from cap? how to load it?

author
paper warrior made it! (author)paper warrior2007-10-22

Yeah, as long as you keep it a little bit nose heavy. You can use a piece of wax on the end for practice rounds. This has the benefit of being formable to an ogive.

author
soccer9270 made it! (author)2007-05-25

the fuse went out as soon as it went in the tube, and the pencil melted so I had to saw it off. I tried a copper tube but it still didn't work. Have you actually done made this work?

Unforgiven_God made it! (author)2006-10-09

well i made it all and i thought i was just supposed to crush up tons of matches and shove them in the pencil, so i did and lit it and all it did was make a big flame, melting half of my pencil

rocket man made it! (author)rocket man2006-12-03

author
usuck made it! (author)2007-02-27

the thread wont burn it loses oxygen once it goes into the tube do i do it wrong? And are matchheads really the ends of matches?

author
paper warrior made it! (author)paper warrior2007-02-28

Amybe covering the thread in gunpowder would help. And yes, thats what matchheads are. Better yet use gunpowder for the propellant. 545 rounds of .22cal costs 14 bucks, lots o' powder.

author
paper warrior made it! (author)paper warrior2007-05-19

You just put a pair of pliers on the slug and the case, and pull em' apart. Thats what I do. Btw, this IS in the not liable category. lol.

does thread actually burn like a wick?

author
ninjaman made it! (author)2007-05-13

I am having a lot of trouble with firing this thing. First, the thread wilts if you try to ignite it. Then, the flame goes out as soon as it goes in the tube(like usuck said). Then, I have almost sucesful launche without a fuse. Could you give me some advice?

author
paper warrior made it! (author)paper warrior2006-11-15

pretty much

author
spacessj made it! (author)spacessj2006-11-16

what if you filled that up with some explosive/flammable substance. you would have a mini RPG-launcher

author
paper warrior made it! (author)paper warrior2006-11-16

You could pack gunpowder and iron-shavings in the cap and use the rocket as a fuse for a flak type thing to use against rc planes.

author
spacessj made it! (author)spacessj2006-11-18

If you then mount that on a rc truck and a planeyou have an nice cocept for war gaming with rc's
