Making a Foam Dart Gun (check legality in your state, ages 18+ only please)

Picture of Making a Foam Dart Gun (check legality in your state, ages 18+ only please)
This whole project was made at TechShop, a nationwide "Do It Yourself" workshop.
Blow guns are not legal in every state or country.  Please check the legality of completing this instructable before continuing.  These foam dart guns can fire a projectile with extreme velocity.  Only responsible adults should complete this instructable.  Do not shoot darts at people!

To build and use this foam dart gun you will need a buy a few things.
-PVC pipe
-foam darts (this build is based upon Nerf brand whistler darts)
-string or twine
-duct tape
-paint is optional

Very few tools are needed to complete the build.
-some kind of saw (hacksaw will be fine, I will use a vertical band saw in this instructable)
-a dremel tool (sand paper will work as well)

Step 1: Purchase of tube

Get yourself some 1/2" inside diameter PVC pipe.  Note that the inside diameter measured with a caliper should be approximately 0.585".  If you are using a different size dart, you may need to change the inner diameter of your pipe.  If you are using a different size dart, measure its diameter (at the widest point) with a caliper.  Allow 0.03" of clearance between the dart and the inner diameter of the tube.
 

BUT ITS NERFY! WHY 18+ !?

I don't want to be responsible for some kid shooting his friends eye out! Or choking on a dart. I also have found out that any projectile powered by a blow gun is illegal in California, so I want to make sure that adults are making these things so they can check legality in their state.

If this is made with intent on using only nerf darts, then it should be safe (to a degree) but I do understand why you put 18 plus.

yea i agree

I was surprised at how hard the darts shoot out of this thing. If kids were to "play" with one of these I see potential danger. This gun should only be used to shoot targets. Thanks for the first comment!
