>working hands and brain

make the blowdart, actually this really isn't a blowgun instructable it's more of a blowdart instructable.
first make a regular paper dar, if you don't know how, refer to http://www.youtube.com/watch?v=Ug0VusClPCs

use the scissors to cut off the small circle of plastic at the opposite side of the point. heavier duty scissors work best here.

this is where you cut off a small portion of the nose of the dart and put the tack into it. Make sure you don't cut to much of front of the dart off. once you put the tack inside, tape the two together.

fit the back of the dart to the tube and cut off the back of the dart to the right size for the diameter of the straw/paper tube.

your pretty much ready to fire. to see it in action go to http://www.youtube.com/watch?v=PV37zek4FAA
