Introduction: Party Popper Rocket Launcher

How to make a fun toy rocket launcher using a party popper.
This is a surprisingly powerful launcher with the projectile penetrating thin cardboard so please use responsibly and be careful when using the razor blade or craft-knife.

would a shorter barrel go further?

it depends how short. the ideal barrel size would be one that is the same internal volume as the amount of hot, pressurized gas created by the popper, so that just when there is no more pressure behind it, it leaves the barrel.i think that if you actually made the barrel slightly longer, it would have pressure behind it for longer, and go faster. however, it all depends on the volume of gas put out by the popper.

nice, i used airsoft bbs

NatNoBrains (author)2011-01-03

The finished thing. Took me a while to find the right sized barrel. Shot OK.

where can I find bluetak?

NatNoBrains (author)Pat_Maroney2011-01-03

Use anything to block up the holes, maybe even gkue, chewing gum...

just put a bunch of airsoft bbs into the pen and a wad of paper presto airsoft back up weapon.

Doesn't it seem like a little too much effort for a 1 use thing? Even though, pretty ingenious and a nice little ballistics toy.

If it's a spring-loaded popper it can be reused:

Colonel88 (author)Fizzxwizz2009-11-29

No, not too much because it is One use and after using it you ccan just throw it away. Instead of tube just use straw and instead of BLU-TAC use some cheap play-doh or something. One use, sorta like a derringer :D

Can you say... THUMBTACK TIP???

badboy123 (author)pyro_122009-05-31

dude u can buy them at almost any grocery store in the toy section

The Red Button (author)badboy1232009-06-02

some states ban any pyrotechnic D: D: D:

temp (author)The Red Button2009-07-28

Like massachusetts. At least, they require you to get a special liscence to sell them. So most stores dont =(. But the ice cream man does =D

Tehevilfluff (author)2008-04-05

Do you have to use the bluetak/gum? If so, are there any replacements for it?

Rotten194 (author)Tehevilfluff2009-06-02

DUCT TAPE!!!!!! I think that would work pretty well, need to go buy some poppers though- for scientific purposes, of course.

lambman64 (author)Tehevilfluff2008-11-25

i bet hot-glue would work

knaven (author)Tehevilfluff2008-04-05

You could try plasticine or even clay - essentially something that will seal and hold the parts together. If you were happy to have the launcher perform just one shot you could even use glue.

pyrosniperfreak (author)2009-04-15

Hey dude, that kinda looks like you faked the part where it goes through the cardboard. You showed the clip of it firing, then you showed the clip of it going through. And those things have like no power at all. I have airsoft guns that won't go through cardboard.

pyro_12 (author)2009-04-09

can u post a link to the order on ebay please

Ben The Builder (author)2009-04-04

Neat Idea, I never knew those little things had so much power, now, if only you could find out how to load them in one after another, maybe like just cut out the confetti and stick the pen all the way in and then use it, less work to change the poppers

Blo0dZsTa (author)2009-01-05

lool i did it an used a bb an i didnt think it would hav much power i put the barrel on my hand an shot it biig purple swelling

RocketManDave (author)2008-12-20

Simple, single use... Kind of reminds me of a tiny panzerfaust! Very good work ;)

lord voldamort (author)2008-10-09

how could you be cruel to a lolipop?

Anton1995 (author)2008-07-09

Great.Love it.4.0

jboppx22 (author)2008-05-03

Mattrox (author)2008-03-10

Looks cool I wonder if it would shoot bb bullets?

jakee117 (author)2008-02-19

nerfer192 (author)2008-01-09

that was pretty cool! and has power too!

PKM (author)2008-01-04

You can see the flash through your fingers in the slow-motion! Sweet :) I'm not normally one for this sort of pyro hack but I love the ingenuity and simplicity.

knaven (author)PKM2008-01-04

The flashes were a surprise when I saw them on screen. Initially when I went through frame by frame in Adobe Premiere there was no flash but when I slowed the footage down suddenly the flashes appeared. I don't quite understand why that should be but it was a nice surprise when I saw it.

Kevvixx (author)2008-01-03

Thats the coolest launcher i have ever seen!
Great Video and Clear Instructions = one awesome instructable!

GorillazMiko (author)2008-01-03

Great video, I love it. Looks easy, I might try it out.

knaven (author)GorillazMiko2008-01-03

Thanks for your comments. If you do have a go don't bother emptying out the confetti, just cut off the barrel with the confetti in it and that will same you a little time.

thejrb (author)2008-01-03

I love the mcgyver theme song. A well put together instructable. Although I might put in steps for printing off and building. Plus one for you.

knaven (author)thejrb2008-01-03

Thank you. Your comments are appreciated.

ker-boom101 (author)2008-01-03

nice i like it but where can i get party poppers here in canada because i was thinking of adding matchead to the popper to burst out burning match heads.....

knaven (author)ker-boom1012008-01-03

Hi, I don't know specifically where you can buy them in Canada, if you can't find them locally I have found that you can buy them on with shipping to Canada. The item number number is 260198134660. A box of 72 poppers (that should keep you busy) costs US $6.25 with US$5.95 postage. I hope that is of help.

ker-boom101 (author)knaven2008-01-03

thank you i just ordered a box of them and i should be busy ill post an instructable soon mentioning you and my thankyouness

knaven (author)ker-boom1012008-01-03

Fantastic. I hope you manage to refine the design and look forward to seeing the results. By the way, I eventually found that you don't need to remove all the confetti from the barrel, just cut off the barrel with the confetti still in it - it saves time.
