Make a Blowgun and Darts with Shoelaces and a Pen

Ever wanted to make a dart and blowgun that you can shoot in the house?

Steps

Gather a shoelace and a pin with a head no bigger than the small plastic part that holds the shoelace from unraveling.
Cut the shoelace an inch above the plastic. Fluff the part of the shoelace that you cut to make "fletchings."
Push the pin through the back of the plastic so the sharp part is facing forward.
Acquire detachable pen for the blowgun.
Cut the end with the tip off.
Pull out the part in the back that nocks the pin. You can cut off the fletchings or keep them on for decoration.

Find a poster of someone or something.
if you can't blow hard enough, simply blow up a balloon, twist don't tie the end and place and hold on end of blow dart. release the twist and balloon will unfurl releasing the air down the blow dart.
You will need lungs of steel for this to work if you use a one inch sewing pin.
Make sure the body of the pen is just {{safesubst:#invoke:convert|convert}} long.

Do not shoot at anyone.
Know the dangers. Many people have inhaled these darts into their lungs. This is a dangerous design because it doesn't prevent that. Save yourself a trip to the hospital and an operation (bronchoscopy) to remove the dart from your lungs. [1]
