> Plastic / Bottle Cap
> Wall Tack / Hot Glue / Clay (not in picture)
> (maybe a small rod like a skewer)
> Grab your pliers and pen!
> Dismantle the pen and keep the cap, ink, and housing!
> (You may need a wooden rod to push out the small end cap)
> Only throw out the end cap!
> Use the bottle, cap or plastic, and lighter.
> In this case I am using the plastic because I threw away the cap on accident!
> If you are using the cap then just screw it on tight.
> If you are using plastic, fuse it together by lighting the plastic and (using pliers or a glove) press the hot plastic to the bottle
> You may also hot glue it down!
> Heat up the scissors or knife and melt the plastic / cap
> The hot metal melts the plastic and allows you to cut with out cracking the plastic.
> (You may want to use the pliers or gloves if you touch the metal)
> Make the hole slightly smaller than the pen housing.
> Using hot glue / wall tack / or clay to seal the pen housing in the hole
> Blow throw the pen and feel for air leaks and repair as needed!
> Repairing the leaks will just be the process of gluing the hole or covering it with clay / wall tack!
> Place the cap on the pen and stomp on the bottle like in the picture at the begging!
> This is my modded pen cap
> Using the lighter I melted a hole at the top of the cap and placed the ink in the cap
> Then I fused the ink to the cap and fused the end shut so ink wouldn't come out!
> The ink can be removed completely allowing the missile to go farther!
> Make sure there are no places for the air to leak in the rocket / missile as well or the pressure will escape and the result is a 4 foot launch!
