Cheap Blowgun (Deadly)

This instructable will instruct on how to make a blowgun that is actually quite powerful, and is made of cheap, easy to find materials. 

You will need:
- A braided cotton lace (like in the waist of a pair of sweatpants)
- A few 2 inch finishing nails (the ones with the tiny heads that come in a strip)
- Some thread
- Electrical tape
- 3 pen tubes
- Scissors
- A pear to shoot the darts at
- A paper clip

This step is fairly simple.  Just tape the pen tubes together end to end.  Make sure all 3 of the pen tubes have the same inner diameter.

The darts are the hard part.  I'll explain how to make them in the image notes. 
P.S.  There are two kinds of darts you can make.  The first, (and best in my opinion) are the fuzzy darts.  The second kind are the tape darts.  The fuzzy darts are made out of a shoelace, fly slightly slower, but are more accurate and don't tumble in the air.  The tape darts fly faster, are less accurate, but they tumble and are useless for a long-range shot.

Push the dart into the mouth end of the blowgun with the nail pointing away from you.  If you are using a fuzzy dart, use a paper clip to push it in until you cant see it.  Once the dart is in the mouth end, take a deep breath, put the tube to your mouth, aim it at your target and blow hard. 

***** I do not take any responsibilty for anybody's stupid ideas involving using this as a weapon or shooting it at a person, animal or something that is not yours.  Actions such as this are proof of your stupidity alone, and are not my fault.*****
