Mar 23, 2007. 9:28 PMThat Hurt This Time says:

Wait, wouldn't it just be better if we fired a stage three hornet from it? It seems like less work, for twice the effect.

Awsome, simple yet efficient, good work.

Oct 2, 2006. 12:34 PMJustListenToMe (author) says:

9 out of ten times it worked for me, and in step 3 the clip is upside down

Oct 2, 2006. 12:16 PMJustListenToMe (author) says:

no it almost always works, and when it doesnt fire you just didnt put them on right and i did test it and paperclips are everywhere now.

Oct 2, 2006. 12:13 PMalexsolex says:

Step 3 : Did you try it ? I'm pretty sure if you release the paperclip like you showed in this step, it will not go very far and stay on the rubber band... You may try to bend it so that the 'external' end of the paperclip make a "V". Then, bend the internal to prevent to hang on the rubber when releasing... I know my explanation is not very good, I lack some english vocabulary to explain myself...
