Not the Italian job kind (although I know how to make that too), but a type of burning paint that can be used to burn whatever you paint into wood, and then scrubbed away. You will be left with a piece of wood with whatever you painted charred into it. Its fun, safe (compared to my other projects), and a gives a good show when you light it.
So half the art is actually the process of making the art.
Step 1: Parts
1. Piece of wood, it will be your canvas
2. Gunpowder http://www.instructables.com/id/EEXOON4E1HEPA8KQNM/
5. Rubbing alchol
6. Pencil and Sharpie
Step 2: Make the paint
In a tupperware container mix 10 parts gunpowder with 1 part dextrin. The amount you will make depends on the size of whatever you are painting. However, it is a good idea to mix only a small amount because you can always easily mix more if you run out.
With the powder in the tupperware container pour in the rubbing alchol. Stir in between pouring, and keep adding rubbing alchol until the gunpowder is about the consistency of acrylic paint. Stir it until all the clumps are worked out and you should have a somewhat homogeneous mixture.
The picture shows the mixture after I added the alchol but before I mixed it.
