pin projection unit

Step 3 Final bits

Thats about all i can think of really.

And how to load it, you just slide the pointy end of the dart err "pin" into the tube and blow...

And please! for the love of god and your own bodies, don't point this at your siblings, parents, room mates, or dog... (cats are free game... they claw you with pins while you sleep, why not return the favor? joking! don't harm anyone or anything....)
