How to Make a Dual Sided Pen!

Intro: How to Make a Dual Sided Pen!

In this Instructable I will teach you to make a dual sided pen. This is an easy 1-5 minute project that actually has some practicality. (It is also a cool trick to play on your friends, More on that later. ) This is my first Instructable so leave comments, but don't be harsh. I came up with this pen when I needed 2 different color pens for school but only had one pen slot in my note book. It is better if the pens are 2 different colors.

Step 1: Gather Materials

This one is easy, all you need is:
2 ball-point pens that are different colors.

Step 2: Remove Ink Tubes

To remove the ink tubes, just twist and pull on the colored part that connects the tube to the pen body.

Step 3: Remove Colored Part From One Tube

Now, twist and pull the colored part away from the tan part on one of the tubes (save the colored part, you'll need it later.)

Step 4: Pop Out End Cap

Now, put the ink stick in and then push down HARD. The little end cap should pop out.

Step 5: Put Colored Part Back on

Just like the title, put that colored part back on the ink tube.

Step 6: Slide Pen Cartridges in to One Tube

First, slide one completed ink tube into the body tube. Next, slide the other one in to the end that you removed the end-cap from ( this might take some work.) And done, your pen is now complete.

Step 7: Tricks

As I promised, the trick you can play on your friend is to put caps on both sides and then ask ,"I bet you $1 you can't guess which end doesn't write." And obviously both ends write and they will be $1 shorter =) .

I hope you enjoyed my Instructable!

    And I was gonna make 1 :( lol. PenSpin™ lol. There is one weakness:

    Unusually, the ink from the other cartridge droops down and off the writing side, so when you try to write with that other side, only some ink goes out. Then, you would have to wait for a few minutes before you could write (in my place, some of the quizzes are done quickly in about 5 minutes, that's the time it takes for my PenSpin™ to recover ink)

    And so, with my almost infinite wisdom (lol), I have made, THE DUOPEN (officially, it's the DuoPen™. PenDuo™ sounds better. I think I might just consider DualPen™... nah)

    this pen was a pen spinning mod called BICtory but still good instructable :D
    sometimes the back plugs or the colored front tip thing are glued on D: but u can put it in hot water for a couple of minutes and the glue melts and allows easier removal :D

    I used my teeth to get the cartridges out of the one pen, if it is too hard try using pliers to break the glue around where the colored part is connected to the white tube. If that does not work, get a different pen. Sorry it took so long to post this, the instructables robot just told me that you had commented =(

    If you cut the ink cartridges in half, they would be easier to insert into the tube. But, good instructable anyway.

    Not really. I cut it with pliers, then just threw the ink cartridge half into the trash before it leaked.
