Make a Lego Rapid Fire Blow Gun

This is a gun that I made that fires small lego pieces by blowing into it.
When I was building it I didn't know how well it would fire.
It has only one glitch:
the amo sometimes gets jamed and to fix the jam, you have to put your finger over the barel and blow to release them.
note: it won't fire with the barel plugged.

Just look at the 3 pics below to build it.
you'll need 25-26 of the amo(see the yellow box below).

...and also how to attatch it.
Just look at the pic below to build it and attatch it.

Look at the 2 pics below to build and attatch it.
