Introduction: Super Simple Knex Blow Gun

About: I am a sixteen year old from luverne MN, and I love to spend my spare time playing with knex, Legos and my xbox. I also enjoy hunting, airsoft, and swimming.

This blowhard gun is probably the simplest knex gun out there. I shoots small green rods ( at least that's what I use) and has a range of about 30-40 feet.
Pieces needed:
28 Gray connectors
1 long Gray rod
Ammo

Step 1: Construction

Take the gray rod and all the gray connectors and assemble them as shown. And you are done. All that is left is to shoot it.

    Instructions were not clear enough to follow. I got my foot stuck in a toaster... :|

    Haha. Yeah I tried to make it longer, or use different pieces, but this surprisingly got me the most power. If you find a way to make it more powerful, please tell

    Have you already built a prototype for that design? If so what is its range?

    maybe try using angle joints and staggering the rods? You could then have one fairly airtight tube all the way along but make it a bit longer
