Do an experiment about air duster gun (2)

We continue to do an experiment about air duster gun.

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 stove-top) comes in. CAREFULLY melt the tip until it's barely soft and roll it on the desktop to shrink the diameter 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 description haven't helped, the pictures should help.
