Picture of Gluphite: Make A Key Chain Pencil
Gluphite is a fairly strong plastic made from glue. It can be used to make a small thin pencil that can be carried on a ring chain or in a wallet. It is cheap and easy to make and give as a gift.

The intro pic shows the pencil on a key chain.

Step 1: How it Works

Picture of How it Works
Gluphite is a simple mixture of Gorilla Glue and carbon graphite. It hardens into a fairly stout plastic that has some interesting qualities including working well as a pencil body and lead.

 
couldn't you just crush pencil graphite into a fine powder and use that?
but the idea is so the stuff doesn't go everywhere and so that you can carry it with you...
I think Madrobot meant using the crushed graphite as a substitute for the store-bought extra-fine graphite, not as a substitute for the keychain.
ya, unconventionalartist is right. so it should work right?
unless you're wiling to sacrifice a coffee grinder for the project I would say no. You'd end up with way too manny lumps in your mix.
Well, you could use a mortar and pestle, and that would grind it up pretty finely.
Actually, I think that would just coat your mortar & pestle in a smear of graphite, giving you far less actual powder than you would get for your dollar than just buying the stuff.

Cool instructable!

I am also interested in this sentence: "The white glue can also be mixed with corn starch or fine sawdust instead of graphite to create a hard carvable plastic that can be colored with oil or acrylic paints." 

Does it mean that i can make low-cost customized casing or prototype with the above composition? Won't the corn starch decay? Will the product be waterproof?

Once again, thanks for sharing this nice instructable!

The starch does not decay, but the gluphite is only water resistant. It also deforms and shrinks as it dries.

For low cost prototypes and casings, I would suggest Oogoo which is waterproof and much easier to work with.
