Legal note: Blowguns are illegal in Canada, Massachusetts, the District of Columbia and New York City.  Check your laws.

Safety notes: Blowguns are surprisingly powerful.  If there is a hard object near or behind the target, wear safety goggles in case of ricochets.  Make sure nobody is near the target.  Even the paper darts can poke out an eye, and certainly the nail ones can do damage.  I do not recommend using the nail-tipped ones outside of a proper shooting range (e.g., an archery range).  Children should be informed that blowguns are weapons and should only be used under close parental supervision. Do not breathe in while shooting or you may have a dart go down your throat, and instruct children to be careful not to breathe in. It can be tempting to breathe in through the nose with mouth on blowgun, but resist the temptation--the dart can go back into the mouth, or worse, then.

I will give instructions on how to make a Fukiya-style blowgun either out of CPVC pipe or a magazine, as well as on how to recycle magazines into Fukiya-style paper-cone blowgun darts of various types (paper-only, wood-tip, nail-tip and cotton-tip), using a pencil with a rubber band method to roll them (while there are other instructions, none of the ones I've seen use this very handy tool which makes good long darts).  I will also give directions for a simple styrofoam target.

While I included instructions for tougher darts, don't sneer at paper-only ones.  I can easily propel them 40 yards or so, and they stick very nicely into styrofoam.

You can make paper-only darts and a paper-only blowgun for office "warfare": you only need an old magazine and stuff you can find around the office, so this is a perfect item for entertainment in the office, assuming that your office rules won't consider this a prohibited weapon.  You can then use the styrofoam from some packaging as a target.  

I will also throw in instructions for hand-throwable darts.  Hopefully you can use those by hand in jurisdictions where blowguns are illegal.

The instructions are divided into four main parts.  First, blowguns.  Second, darts, starting with the basic paper dart which you should master first.  Third, a target.  Finally, a few notes about shooting.

Ingredients and tools for basic darts
  • glossy magazine, ideally with fairly lightweight paper (I used This Old House with success)
  • glue (e.g., white paper glue--I use Aleene's tacky glue--but for something more durable you can consider using water-resistant wood glue, like Titebond III)
  • pencil (or pen or other narrow cylinder)
  • rubber band
  • scissors or, better, box cutters
  • optional: steel ruler
Ingredients for specialty darts
  • wood-tip: toothpicks
  • short-skirt: bamboo skewers
  • metal-tip: #16 1-1/4" brads for ordinary use, or 12- or 14-gauge silver wire for zombies/werewolves (see note below)
  • hand-throwable: heavier magazine paper and some cardstock from magazine mail-in inserts or a magazine cover
  • cotton-tip: cotton swabs (e.g., Q-tips)
Ingredients for blowguns
  • CPVC pipe blowgun: 1/2" nominal CPVC pipe, at least three or four feet in length, plus pipe-cutters or hacksaw, and sand-paper
  • 100% recycled magazine blowgun: stapled magazine, ideally with heavier paper
Ingredients for target
  • 3/4" styrofoam, at least 8" x 8"
  • hot knife, or candle/burner and old hacksaw blade or some other thin, fairly rigid, long metal thingy
  • permanent marker
  • pin/nail/toothpick
  • magazine cover
Zombie and werewolf note: Use the metal-tip dart instructions, but instead of a nail, use sharpened 12- or 14-gauge silver wire (I would sharpen with a file or a Dremel-type tool).  I recommend roughing up the side of the wire with some coarse sandpaper so that it glues better into the paper skirt.  You could try both pure but soft silver (e.g., available here) and less pure but harder silver with more penetrating power (e.g., here).  Due to the lack of zombies and werewolves in my area, I have not been able to figure out which one is more effective.  If you go for the harder silver, you can get a foot for $30, which should be enough for eight darts.

Step 1: Blowgun: CPVC

Find CPVC pipe.  Choose the straightest you can find.  Don't worry about a small bend.  When shooting, you can turn it so it bends up, and gravity will bend it downward to compensate.

Japanese Fukiya blowguns have an inner diameter of 12-13mm.  In the US, 1/2" nominal CPVC pipe does the job.  

Cut the pipe (with hacksaw or, more easily, pipe-cutters) to length.  Japanese Fukiya tournament length is 120cm, though in the US you can use 4 feet.  For children or shorter-distance practice, you can cut to 3 feet or even 2 feet.  A one-foot pipe won't be very accurate, but one can still have fun with it.  The longer the pipe, typically the faster the dart will go on exit and hence the more level the trajectory, though (a) you will have more difficulties with sag, and (b) once it gets too long, you won't be able to fill it with air from your longs quickly enough.

Sand the inside of the cut to make sure darts don't get slowed down by burrs. 

If you want to share a pipe with someone, for reasons of hygiene you might want to mark which of you blows from which end.  These Fukiya-style blowguns don't have mouthpieces so they can are bidirectional.

A more expensive option, resulting in a straighter but heavier blowgun, is to use copper pipe.  
<p>When I was a kid we used to add an acacia spine to the dart tip, holding it in place by dripping molten wax inside the tip. Real killers, would stick in a tree at 30 ft.</p>
<p>check out mine:) https://www.instructables.com/id/Paper-Blowgun-Darts-my-First-Intructable/</p>
<p>i favorited this</p>
<p>for a mouth piece u could drill a hole in the middle of a end cap and stick that on it</p>
<p>i will make these for darts</p>
<p>cool vid,</p><p>i am making a blow gun for the fort i'm building with my friend;)</p>
<p>This is a great tutorial and the right way to build paper darts.</p><p>Made a quick video myself a few days ago.</p><p><a href="https://www.youtube.com/watch?v=dgt8EheyjqY" rel="nofollow">How To Build And Launch A WMD (Wrapped Magazine Dart) - YouTube</a></p>
بجد رائع هداك الله الى الاسلام :) وطريق الحق
cool I use ear plugs for my darts I am work on a blowgun right now that is giving me some trouble but it good I am having trouble with making the mouthpiece some how I want to put a safety of some kind on the mouthpiece any ideas for this I would really appreciate any ideas
I assume the point of the mouthpiece is to keep you from breathing in the dart accidentally.<br><br>I would think it would be hard to breathe in an 8-inch dart like mine, though I suppose one could do it. (I sometimes accidentally got half an inch of it in my mouth, but that's all.) However, the earplugs do sound like more of a risk. <br><br>Perhaps a CPVC cap sized to go on the outside of the tube with a cross-hair pattern cut on it?
Wow... That's really dangerous.
Blowguns illegal ? My childhood would have been so much boring... :) <br> <br>I did once made darts using thorns. Could shoot those suckers into a piece of wood.
Yeah, Canadian, Massachusetts, California and NYC laws are crazy here. Roll a piece of magazine paper for purposes of shooting paper darts, and you're a criminal in Canada and California (I didn't check the wording on Massachusetts and NYC).
I can thank my lucky stars I moved out of California when I was 2 months old.
holy moly that is insane
Its kinda difficult to make a magazine blowgun
I voted for you
It's also been getting crazy here in Maryland. A kid chews a pop tart into the shape of a gun and he's treated like a criminal. The school won't expunge his record either. <br> <br>http://www.nydailynews.com/news/national/boy-suspended-gun-shaped-pop-tart-lifetime-nra-membership-article-1.1359918 <br> <br>http://cnsnews.com/blog/gregory-gwyn-williams-jr/boy-suspended-pop-tart-gun-loses-appeal-have-record-expunged <br> <br>My friends and I spent a part of February and March, taking time off from work to fight some of the stupidest gun laws proposed up in Annapolis testifying in the Legislature. So did several thousand other people. We kept those legislators up until 3am, We had logic and reason on our side. We lost. <br> <br>And then there is this kid who gets suspended for a pea shooter: <br> <br>http://www.educationadminwebadvisor.com/headlines/article/peashooter-zero-tolerance-lawsuit-denied-day-in-supreme-court <br> <br>This normal kid behavior is classified as &quot;violent criminal conduct&quot;. <br> <br>And how is this for tolerating diversity: <br> <br>http://www.theepochtimes.com/n3/114808-jared-marcum-boy-who-wore-nra-shirt-faces-jail-time/
looks awesome
I've always loved making these.
I will definitely think twice before going to war with your clan! :-)
