The Office/school Bow and Arrow

this is my first time at submitting something like this so give me a break if its hard to follow.
this is basically a bow and arrow made out of kilometric pens and some rubber bands i found at school but i WARN!!!!!! all it is powerfull and will leave more that a pen mark on a co worker or school friend so point away from anything living

u will need:

3 kilometric pens
3 large rubberbands
duc tape
sccisors or a stanley knife

get two of the three kilometric pens and one of the large rubber bands and tie the two kilometric pens together do the same with the other side

now u have that set up get the top of the pen the part that holds the pen ink inside pull that out
this is going to be out aimer
first cut the top off just a little bit just enough that the pen in can slide through with ease but not too much that it is lose

then tape that pen head to the center of the bow construction made in the previous step
now u have a working aimmer

now u have that completed moving on to the string that gives the arrow the propulsion

first cut the rubberband so it becomes a long ruber strip
2nd tie one end to the arms of the bow and do the same for the other side
it should look something like the pic

now ur done get the inside ink and thread it through the aimmer pull bac on the rubber band strip while holding the pen ink. but dont pull bac till it is out of the aimmer just enough and let go
as i said in the beginning becareful were u aim it is dangerous

if there are any improvements u can make please tell me i would like to know
