i cant wait to take on to school blake is so dead!!!

ramicaza (author)2011-10-29

lol its not that dangerous chill. I did this a few years ago but wrapped the wannabe breech in tape... Before I wrapped it in the tape It exploded in my hand but it only made a few small cuts. That was with a fire cracker! this is a mere party popper.

dosRedLight (author)2011-07-04

really cool

ilpug (author)2011-03-19

THIS IS EXTREMELY DANGEROUS!!!! do not hold this in your hand when firing. i fired mine (thankfully in a testing box) and it exploded, sending shards everywhere. i used the exact same methods as you.

You can buy everything you need at the dollar store or part city( only $10 for 500 in north carolina and im pretty sure south carolina.) except for bb's, but u can use spitballs, erasers, or anything really

finnster (author)2008-05-13

a papermate eagle M is much easier to take apart

Big Bubba (author)finnster2008-08-23

wanna make one finn?

finnster (author)Big Bubba2008-12-28

I tried, the pen was to big, I'll try again next time I get "PPs"

blugyblug (author)2008-11-24

Is this only one shot? Then you have to load in another popper thing and then shoot again? Because you said " load the string in" What about the explosive bit?

cheezydog100 (author)2008-09-27

i didn't ask for permission i needed a driver to brng me to the store for the popper thing

cheeseboy (author)cheezydog1002008-11-04

c'mon find an excuse to go, and buy it then, follow my motto

when honesty fails

btw Cheese rocks =)

Kryptonite (author)2008-03-07

holy ****!!!

i just made 1 and the end of the pen gun u stick the end back in back fired and hit my finger, leaving a round, bleading mark. not to mention the bang!!!
it made when it off, im lucky my parents didnt hear that or i wuda been in serious trouble, considering i just sliced my fingers open with a knife cutting the rubber out of a pencil for a bullet.

im not sure what happened to the rubber, but my finger hurts like hell!

nice instructable, even though the idea is hell dangerous. trust me, the explosives in a party popper can really wreck ur evening

Kryptonite (author)Kryptonite2008-03-07

for every1 that's gonna try this, dont put anything directly behind it as it goes off, cuz the end of the pen cud probly go through a line of coke cans and come out the other side fast enough to kill. no, serious.

stuffman366 (author)Kryptonite2008-05-23

He is serious so tape the end on

codz30 (author)2008-04-30

No, you copied mine.
You made yours " Aug 28, 2007"
I made mine "Jun 1, 2007"
June comes before August, i win!-Simple-and-Cheap!/

tac135 (author)2008-04-12

I made one of these once, except i used a small firecracker instead, and i used an eraser off the end of a pencil as ammo, it made a VERY loud bang, and the eraser shot out of my backyard.

X_D_3_M_1 (author)2007-11-02

this is FREAKIN LOUD! I was deaf for 5 min. its shot a SPITBALL and DENTED A CAN O COKE!

nkk07 (author)X_D_3_M_12008-02-02

mine shoots throughthe can.

nkk07 (author)2008-02-02

i made this in about 5 seconds without tape or your instructable. p.s. i am angry bcause i would have posted mine and it would have been great but of course you had to post your rubbish one mine uses a mechanical pencil posting the pictures of the carnage soon!

sputnik3373 (author)2007-11-05

i made one of these with 4 barrels and a handle. instead of taping over the end, get a pen where the bb gets stuck loosely about halfway down, then use a lollypop stick or something as a ramrod. you could also load 3 bullets at once for a shotgun(ish) effect. oh yea, dont push the bb too tight or the pen explodes... and it hurts lol.

getadicted93 (author)2007-10-23

i made one and it was loud and smokey and my mom got really mad, it was great. hahahaha, but try using pull string firewrorks, they are cheaper and you can put 3-4 in

The_Kangsta (author)2007-09-08

u should make a video for it

judelizowski (author)2007-09-03

Great instructable! i made one of these and i shot the bb thru a soda can!!!
