Intro: Super Simple Knex Blow Gun
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.
28 Gray connectors
1 long Gray rod
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.
