BoomeRING CataPENt

This is an extraordinarily simple weapon that shoots keychain rings or paperclips or anything else that you can use as ammo. I accidentally discovered this and it took me way less than five minutes to build.
BUT TRUST ME, THIS THING ROCKS!!!!!!!!!!!!!!!!!!

Supplies:
MEDIUM-LARGE BINDER CLIP THINGY
PEN WITH METAL CLIP ON CAP (PREFERABLEY A UNI-BALL PEN)
KEY CHAIN RING or Other AMMO

You don't have to take the pen apart! So go ahead, use your favorite pen.

Step 1: STEP 1

1: Take the BINDER CLIP THINGY and clip it over the cap so that one of the metal things that you squeeze together to make the BINDER CLIP open is ontop of the metal clip on the Pen Cap, but the pinchy part is under the metal clip of the Pen Cap.
I will add a diagram if I can make one on my computer later.

Step 2: STEP 2

2: Put the Key Chain Ring over one of the metal squeezer thingers and pull back the sqeezer thinger. Let go and the ring should fly off, flipping through the air and making a very cool noise.

WARNING: THIS IS DANGEROUS! IT IS VERY HARD TO AIM AND THE RING IS UNPREDICTABLE, SIMILAR TO A BOOMERANG!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
