Step 1Preperation

Preperation
1. Remove the tip of your Bic pen by biting and pulling or using pliers.

2. Remove end cap ( Be creative, theres no best way, I just cut it off, but make it a clean cut! )

Barrel Is Complete, Set Aside.

3. Remove the felt tip of the Crayola marker ( Messy, dispose of wisely )

4. Punch small hole in the rear of the marker and insert the screw. This will serve as a 'handle' to remove the end cap.

5. Pull, thus removing the end cap of the marker. Do not discard, you will need it.

6. Remove the ink tube inside the marker ( Again, be creative, tweezers, etc., discard of wisely )

7. Poke two small holes 1mm in diameter about 3/4in. from the rear of the marker at the 12 and 6 o'clock.

The Chamber Is Complete, Set Aside.

8. The peizo electric igniter probably is still inside your BBQ Lighter, so we're going to need to remove it with the wires intact.

9. Usually the igniter comes with one wire and a contact pad, if so find another wire about the same thickness and attach to the contact pad. ( Once again, be creative )

10. Strip the ends of the wires leaving about a millimeter of exposed wire.

Best projectile for these mini spud guns:
Those tall, skinny Lego antennas. The ones that can flex a little bit. The base of the antenna that interlocks with other Legos is perfectly matched to the inner diameter of a BIC pen tube. Shooting these things is dangerous (these shoot WAY faster than any q-tip; you can't even see them fly they go so fast. I shot one at a fabric couch and it penetrated the whole way to the base of the antenna). The base also acts like a badminton birdie and stabilizes the long, thin antenna in flight.

I've tried firing spitballs, pen tips, airsoft BB's (a bit too small), and a .22 cal bullet (which only went a few feet and much slower). so far spitballs are the best.

if you put rubbing alcohol as fuel it whistles and launches it 1 inch

well.... i made it... its purdy cool and fun to shoot!! but my first time firing it i tryed using Rave hairspray. its flamable so i figurd it would work. and it did barly!! So i decided to find a diffrent propelent. i found out that bug spray for flies and horse flyes works ALOT better.... but remember never put to much of any propelnt in the gun. not because its to powerfull. but because it just wont fire!!!(cuz no oxegen to burn). but the only problem i have with it is that the BBQ ignighter keaps running out of battry! i can maybe get only 8 shots out of one igniter!  is there any other way or thing to use as a igniter???

you have way too much time on your hands.

i agree with Applecore807
not everything is a "waste of time" or a matter of having too much time on your hands but hes really beating most cavilians and hes not on facebook all day hes doing somthing useful with the time on earth mabey hes like some of us and likes to find out what happens if u mix hairspray and butane with an oxygen level and see what ratio propels farther so i agree with everyone in this convo except you Drstoopid
Apr 22, 2010. 4:17 AMApplecore807 says:
To be honest Drstoopid im sick of people saying that, if you learnt a good english class you'd know that were stuck in a matrix which is a jail that we cant see of touch. This ideology of growing up getting a job pumping a female having a kid and increasing your land property untill you die is quite wrong and hence a matrix. Sure he could do oher things like go to the mall but really he has found something unique and creative and has spent some time  teaching us. Too much time on your hands is very shallow for something that has a deeper meaning.

i cant find a electric lighter just butane what do i do
Sep 9, 2010. 11:06 AMDISTURBED1 says:
butane will also make a bigger boom therefore more distance
Aug 13, 2010. 12:40 PMDISTURBED1 says:
get one of the long tipped lighters and unscrew the screw in the back inside take wire cutters and cut the wires by the butane follow the cord back thats the thing that makes the spark and obviously when the butane goes past the spark u get fire... sorry didnt mean to give the whole anatomy lol its a very simple thing to do.

go to ace hardware and ask for a grill ignitor, it's the same but bigger and it has a cool red button.
