i am not responsible for anything you hapen to do with this. it would be a good idea not to aim staples at people, by the way.
P.S. (this is my first instructable, please help me out with constructive critism. Thanks!)
If you enjoyed this ible, you'll really like my pencil ballista:
Step 1: Materials
What you need for materials is:
-A box of 12 or more pencils(1$)
-tape (I used electrical tape) (50 cents)
-rubber bands (1$)
-film canister for counterwheight (I used pill bottle ) ( fill with whatever, fishwheight,rocks, batteries, ect.)
as for tools, all you really need is:
-Drill or dremel tool with really small drillbit (about the width of paperclip)
-exacto-knife or pocketknife
-glue gun and glue
Step 2: Make the Frame Part One
now, cut an indentation about 3 inches above the eraser end of the frame on both sides. then, trim another pencil to fit in these, so that you end up with an A-frame shape. (you should have two A-frames now.) Next, drill a hole in the top of the A frame where the two pencils are joined.
Step 3: Make the Frame Part 2
Step 4: Make the Throwing Arm
then, you drill a hole at each end and one about three inches up from one side paralel to the other two.
after that, cut a piece off of a paperclip about two inches long. then, secure it to the longer end of the arm with rubber bands or glue.
Step 5: Make the Counterwieght
then, bend a strong paperclip into the shape below. thread the paperclip shape through the hole closest to the hole in the middle of the arm so the arm is in the raised part of the shape.
you then thread the ends of the paperclip into the holes in the container.
Step 6: Make the Sling
to make the actual sling, take two pieces of electrical tape about three inches long each and stick them together. cut a tiny hole in each end of the sling. then, tie one legth of string through each hole as shone.
Step 7: Finish It Up!
Hooray! you finished the Pencil Trebuchet!
fyi: (you can also make a realease system out of string and paperclips.please, if you have any ideas on a good reasease system, please post a pic!)
