Introduction: Universal Knex Grenade Launcher!

I have seen all sorts of k'nex grenades. and i think at least one launcher but they aren't really universal.
What makes my launcher unique is that it fires almost any knex grenade.

Step 1: The Base

To build the base you will need:

-5 blue rods
-1 blue+grey double clip.
-2 yellow rods
-1 grey rod
-1 black end clip
-2 grey clips

assemble it by looking at the picture bellow. It's very simple.

Step 2: The Ram

This step shows how to build the ram.
you will need:
-1 white connector
-3 white rods
-one (or 2) elastics NOTE: if using a spring don't put elastics on!
-2 grey connectors

Follow the pictures to put it together.

Step 3: Put Together

You will need:

-completed base
-completed ram

follow the pictures

Step 4: Testing Phase.

Now for the fun part... testing!

just thread on a grenade with a central hole through it or you can just launch the ram.

The pictures just show some ammo on it.

Nice but too many rubber bands snaps the rod, not enough and it wont move XP. Good idea though.

You might want to post the completed gun as the main photo, not the parts list :-)
