Universal Knex grenade launcher!

Picture of 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 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.

It only fires like 12cm for me :(
Nice but too many rubber bands snaps the rod, not enough and it wont move XP. Good idea though.
just reinforce the rods. simple...
