Air Duster Gun

Step 2 Pen to Barrel

Now we have everything lets get going. Take the pen apart as shown. You don't need anything but the outer casing and the pointy plastic tip. Take the spring and flick it across the room for you to find later (or don't).

Now take the plastic straw from the air duster and stick it into where the ink tube was not so long ago. It probably wont fit too snugly so this is where the lighter (or stovetop) comes in. CAREFULLY melt the tip untill it's barely soft and roll it on the desktop to shrink the diamater of the tip to fit the straw fairly snugly.

It should be fairly difficult to pull it off of the straw because it will be holding pressure later. Now we need to finish up. If my vague discriptions haven't helped, the pictures should help.

Would an airsoft BB fit in there? That would hurt a lot more!

I bet it would.....

I have made plenty of airsoft guns with pens like that, and airsoft BB's fit fine in them. The only problem that I can think of with an airsoft BB is that the compressed air might go right past the BB, so you might want to use some oil as in step 3.
