Make an Eraser for a Dry-erase Marker

About: Ask me questions. I know the answers.

So, the other week I was sitting through class at the community college trying to keep up with what the instructor was saying. I noticed she kept having to put her book down every time she needed to erase something, taking up precious minutes of class time. I thought, "hey, I have that problem too, why don't I figure out some way to make life easier."
I thought maybe a third arm would work but I was too lazy for that. I made this instead. :-P

This really isn't all that high tech or difficult, but I made it, so I'm going to share it.

Step 1: Materials

You will need:
-an old whiteboard marker that doesn't work
-something soft to use as the eraser, I just used a piece of an old eraser, but a piece of cloth would work too.
-a saw, or something to cut with.
It should take about 5 minutes to make this, plus drying time.

Step 2: Open It Up

Open the marker. I used some pliers and just pulled the back off. Don't worry if you gum up the back of the marker, you wont use it.
Now, carefully pull out the part that holds the ink and the marker tip, so as not to make a mess.

Step 3: Cut and Glue

Cut the marker wherever seems best. Try to cut straight, but its fine if you don't. You can always file it down if you're OCD like me. :-P
Next, you need to glue the eraser to it, I used super glue but I don't think it really matters. If you're using something else besides a piece of eraser, like a piece of cloth, then you can use a square of cardboard with the cloth on top of that.

Step 4: Use It!

Let it dry. Now you have yourself a new eraser made from parts you were going to throw away anyway! Just attach it to the back of the marker and impress people with your resourcefulness.

    You could probably make a coil of cloth or felt and fit it into the cap, for a simple solution. No glue, no sawing.

    Very kewl. I don't use that type of marker often, but I can see where it would come in handy to have an eraser.

    Why bother with the sawing? IE, couldn't you just glue the eraser to the spare cap, or the marker itself?

    Good idea.
    As ®SkankinCow your college bought the wrong markers (these things can be bought).

    I've been thinking of the same thing! Hah, but with considerably less finesse in the execution. I like the use of the dead marker--far better than just gluing the eraser onto the back (as I was planning). And yeah, as you mentioned to another commenter, building>>>buying.
